California is preparing to ask voters a deceptively simple question: should billionaires pay a one-time tax equal to 5% of their wealth? Supporters argue that a relatively small group of extraordinarily wealthy people could provide billions of dollars for essential public services. Opponents warn that the proposal could drive away entrepreneurs, discourage investment, and ultimately leave the state collecting less revenue than expected.
The debate exposes a fundamental problem with modern taxation. Billionaires can accumulate enormous fortunes without receiving anything resembling an ordinary salary. Their wealth may be held in company shares, private businesses, investment partnerships, trusts, and other assets that appreciate without generating immediately taxable income. They can also borrow against those assets, transfer them between entities, and use sophisticated financial structures that ordinary taxpayers rarely encounter.
That makes taxing the rich more complicated than simply increasing tax rates. Governments must decide what counts as wealth, how to measure it, when to collect the tax, and how to prevent avoidance without creating unnecessary economic damage. Even if those problems can be solved, another question remains: will additional tax revenue actually translate into better public services?
The real challenge is not choosing between taxing billionaires and leaving them alone. It is designing a system that taxes extraordinary economic advantages fairly, collects revenue reliably, and puts that money to productive use.
California’s Proposition 40: The Billionaire Tax Debate
California’s Proposition 40, scheduled for the November 3, 2026 election, would introduce a one-time wealth tax on qualifying billionaires. Under the proposal, individuals who were California residents on January 1, 2026, and met the relevant wealth threshold would owe a tax equal to 5% of their covered net worth. The liability would become payable in 2027, although taxpayers could spread payments over five years at an additional cost.
The proposal is intended primarily to finance healthcare. According to the California Legislative Analyst’s official assessment, 90% of the revenue would have to be spent on public healthcare services, while the remainder would support education, food assistance, and administration. Real estate, pensions, and retirement accounts would generally be excluded from the calculation.
Supporters estimate that the measure could collect approximately $100 billion from California’s billionaire population. That is an extraordinary amount of money, particularly when healthcare budgets face significant pressure. However, the Legislative Analyst’s official forecast is more cautious, projecting tens of billions of dollars in temporary revenue rather than guaranteeing the proponents’ estimate.
The appeal is understandable. Someone worth $10 billion would remain extraordinarily wealthy after paying a $500 million tax, assuming the entire fortune were included in the taxable base. Meanwhile, public hospitals, schools, infrastructure, universities, courts, and research institutions all contribute to the conditions that allow private fortunes to grow. Even the most successful entrepreneur does not build a business independently of the society in which it operates.
There is nevertheless an important distinction between identifying substantial wealth and successfully collecting tax on it. California’s billionaires are unusually mobile, and the state’s income-tax system already depends heavily on high-income residents. The official fiscal analysis acknowledges that departures could reduce future income-tax revenue, potentially offsetting part of the temporary windfall. Asset valuations, exemptions, legal challenges, and collection costs create further uncertainty.
The measure’s residency date also complicates claims about billionaires leaving California. Relocating after January 1, 2026, would not necessarily eliminate liability under the proposal. Whether a taxpayer owes the levy depends on the actual residency and ownership rules, their legal enforceability, and the facts of the individual case. Reports of wealthy people moving elsewhere cannot automatically be translated into a corresponding loss of taxable wealth.
Proposition 40 also faces political and legal uncertainty. Two other measures on the November ballot, Propositions 41 and 42, contain provisions that could conflict with its operation. If competing measures pass, their interaction may depend on California’s rules governing conflicting initiatives and potentially on subsequent litigation.
There is a deeper fiscal problem as well. A one-time tax creates temporary revenue, while healthcare, education, and other public services require continuing expenditure. Even an unexpectedly successful collection would not permanently resolve structural budget pressures.
California therefore illustrates both the strongest attraction and the greatest difficulty of billionaire wealth taxation. Concentrated fortunes offer an enormous potential tax base, but a tax must remain effective after accounting for legal structures, economic behavior, and the practical costs of collection.
Why Billionaire Wealth Escapes Ordinary Income Tax
Most employees encounter taxation through income. They receive wages or salaries, their employers report those payments, and governments can collect taxes regularly through withholding. The taxable amount is relatively straightforward because the transaction involves a recognizable flow of money.
Billionaires often become wealthier through a completely different process. A founder may own shares in a company whose market value increases from $10 billion to $20 billion without selling a single share. The founder has gained $10 billion in wealth, but that increase is generally an unrealized capital gain rather than income immediately subject to federal capital-gains tax.
This distinction between wealth and taxable income is central to the debate. A professional earning a substantial salary may pay significant income tax every year, while an investor whose assets appreciate by a much larger amount can defer capital-gains taxation until those assets are sold. Business ownership, retained corporate earnings, partnership arrangements, and other financial structures can widen the difference between economic gains and income reported on individual tax returns.
A 2025 National Bureau of Economic Research study using administrative tax data estimated that the approximately 400 wealthiest American households faced an average total effective tax rate of 24% during 2018–2020. Using the researchers’ measure of economic income, the corresponding figures were 30% for the population overall and 45% for top labor-income earners.
Those comparisons require care. The researchers included taxes beyond individual federal income tax and measured income more broadly than ordinary taxable income. The estimates are not simply the percentage of annual salary appearing on a tax return. Nevertheless, they demonstrate how the taxation of business ownership and asset appreciation can produce results that differ significantly from the headline rates in the tax code.
The study also identified important mechanisms behind the difference. Companies owned by extremely wealthy households often distributed relatively little income as dividends, allowing owners to benefit from appreciation without immediately realizing taxable personal income. Some pass-through businesses also reported taxable income that differed substantially from their economic performance.
This is not evidence that every billionaire pays little tax or that unrealized gains are equivalent to cash. Investments can decline, assets may be difficult to sell, and business owners can face substantial corporate and personal taxes through different channels. The problem is that a tax system organized primarily around realized income may not consistently capture increases in economic resources among people whose wealth is concentrated in appreciating assets.
A wealth tax attempts to close that gap by taxing the assets themselves, regardless of whether their owners have sold anything. Its attraction lies precisely in reaching wealth that conventional income taxation may leave untouched for years or decades.
Why Wealth Taxes Are So Difficult to Administer
A wealth tax looks simple when the assets are publicly traded shares. A government can observe the market price, determine the number of shares owned, subtract relevant liabilities, and calculate the taxable amount. The challenge emerges when the fortune consists of assets without clear market prices.
Imagine an entrepreneur who owns a private software company. A valuation suggests that the company is worth $10 billion, but the entrepreneur has only $10 million in readily available cash. If an annual wealth tax required payment of 5% of the company’s assessed value, the hypothetical bill would be $500 million. The founder’s wealth would be enormous on paper, but the necessary cash would not be immediately available.
That creates two separate problems. First, the government must establish a defensible valuation for a business that may have no publicly traded shares and no recent comparable transaction. Second, the owner must obtain liquidity through dividends, borrowing, selling shares, or disposing of other assets.
Private-company valuations depend on assumptions about future earnings, discount rates, growth prospects, and comparable businesses. Different experts can reasonably reach different conclusions, and taxpayers have incentives to favor lower valuations. Intellectual property, artwork, complex partnership interests, closely held businesses, and some trusts introduce similar difficulties.
The government therefore needs independent assessment procedures, disclosure rules, enforcement resources, and mechanisms for resolving disputes. Taxpayers may respond by hiring lawyers, restructuring ownership, exploiting exemptions, or challenging assessments in court. The administrative effort can become especially expensive when relatively few taxpayers hold extremely complicated portfolios.
Liquidity creates another tension. Selling assets to pay taxes is not inherently unreasonable, particularly for billionaires who possess considerable financial resources. However, requiring sales during unfavorable market conditions can distort investment decisions, and forced liquidation of private-business interests may be particularly disruptive. Borrowing to cover tax bills introduces leverage and financial risk that would not otherwise exist.
Payment installments, valuation discounts, carefully defined exemptions, and deferral arrangements can address some difficulties. Yet each concession creates its own trade-offs. Generous exemptions narrow the tax base, while deferred payments can reduce the reliability of collections or create opportunities for further planning.
Mobility adds another layer. Wealthy individuals may have residences and investments across several countries, allowing them greater flexibility over tax residency than people whose jobs and family circumstances tie them to a particular place. Tax changes can influence where they live, establish companies, and make future investments.
Not every billionaire moves because of taxes. Family relationships, access to skilled workers, business networks, universities, infrastructure, culture, and quality of life can be more important than a particular tax rate. Nevertheless, the behavior of even a relatively small number of exceptionally wealthy residents can matter when the expected revenue depends heavily on their fortunes.
The OECD’s review of net wealth taxes identifies administrative complexity, avoidance, capital mobility, and efficiency concerns among the reasons many countries reconsidered these taxes. It also recognizes that carefully designed wealth taxes can serve revenue and redistribution objectives, depending on how they interact with the rest of a country’s tax system.
The important conclusion is not that wealth taxes are impossible. It is that taxing a stock of assets requires a different administrative system from taxing a regular flow of income, and the effectiveness of that system depends heavily on its detailed design.
What Europe’s Wealth Taxes Actually Teach Us
Europe provides one of the most useful tests of wealth taxation because numerous countries have experimented with it over several decades. In 1990, 12 OECD countries maintained individual net wealth taxes, but most subsequently abolished them. Today, Norway, Switzerland, and Spain remain prominent examples of countries retaining recurrent taxes on net wealth.
This retreat is significant, but it does not establish that every wealth tax loses revenue or destroys economic growth. Countries introduced, modified, and repealed these taxes under different circumstances. Their experiences must be understood alongside income taxes, capital-gains taxes, inheritance rules, enforcement capacity, and broader economic conditions.
France introduced a broad wealth tax in the 1980s, subsequently repealed and reinstated it, and eventually replaced much of its former system with a tax focused on real-estate wealth in 2018. The earlier levy generated controversy over valuation, wealthy emigration, investment incentives, and economic competitiveness. Supporters regarded it as an important tool against wealth concentration, while critics argued that its costs and behavioral consequences undermined its effectiveness.
France’s experience demonstrates how politically difficult comprehensive wealth taxation can become. However, estimates of revenue lost through emigration depend on assumptions about who left, why they moved, and what taxes they would otherwise have paid. They should not be treated as direct measurements proving that the government necessarily lost more than it collected.
Sweden also abandoned its wealth tax, repealing it in 2007 after concerns about capital mobility, avoidance, and economic competitiveness. The decision formed part of the country’s broader evolution in capital taxation. It illustrates why a government can support extensive public services and redistribution while choosing not to levy an annual tax on every individual’s net worth.
Spain offers a different model. Its wealth tax includes regional administration and variations in allowances and reliefs, creating important differences between places such as Madrid and other parts of the country. Some regional governments have historically offered substantial reductions, but national solidarity-tax arrangements have complicated the ability of the wealthiest residents to avoid these taxes entirely. It is therefore misleading to describe selected Spanish regions as having unconditionally abolished all wealth taxation.
Switzerland is particularly revealing because it combines recurrent wealth taxes with a comparatively favorable approach to certain other forms of capital taxation. Wealth taxes operate primarily at cantonal and municipal levels, meaning rates and allowances differ by location. Private capital gains on movable assets are generally exempt in many ordinary circumstances, although important exceptions apply, including professional trading and other classifications.
Consequently, Switzerland’s wealth tax cannot be evaluated in isolation. An investor may pay an annual levy on assets while receiving more favorable treatment on certain capital gains than would be available elsewhere. Some qualifying foreign residents may also use expenditure-based taxation, subject to specific eligibility and cantonal rules. That arrangement cannot be described as an unconditional escape from wealth taxes for everyone who moves to Switzerland.
Norway presents perhaps the most contested example. It imposes a recurrent wealth tax and has experienced departures among wealthy entrepreneurs and investors following increases in the tax burden. Critics argue that taxing business ownership can reduce investment capacity, encourage emigration, and place disproportionate pressure on founders who hold illiquid assets.
Some affluent Norwegians have relocated to Switzerland, where the overall tax treatment of wealth and investment may be more attractive. Their departure can reduce future income-tax receipts and potentially affect investment and business activity. Those consequences deserve attention even when the government continues collecting wealth-tax revenue.
However, the claim that Norway’s wealth tax simply loses money is not supported by the available revenue evidence. Reuters’ examination of Norway’s wealth-tax experience found that wealthy residents had indeed emigrated, but wealth-tax revenue had also increased, reaching approximately 0.6% of GDP. The government defended the tax as a contribution to redistribution, while business owners disputed its effects on entrepreneurship.
These findings do not settle every economic question. Higher collections do not prove that the tax has no adverse effect on investment, just as emigration does not prove that the tax raises no net revenue. A complete assessment must consider direct receipts, other tax revenues, compliance costs, economic activity, and distributional outcomes.
Norway also occupies an unusual economic position. Its immense petroleum revenues, sovereign wealth fund, and established public institutions create fiscal circumstances that most countries cannot replicate. Understanding how Norway converted its oil wealth into lasting national financial assets helps explain why its broader tax system operates within a very different economic framework from that of California or most European countries.
The European experience ultimately supports a more sophisticated conclusion than either blanket approval or rejection. Wealth taxes are difficult to administer and can influence migration and investment, but their outcomes depend on thresholds, exemptions, valuation methods, enforcement, and the broader tax structure. A policy that operates tolerably in one country may produce much weaker results elsewhere.
Taxing the Buy, Borrow, Die Strategy
One of the most distinctive advantages available to wealthy asset owners is the ability to obtain spending money without selling investments. A billionaire who sells appreciated shares generally realizes a capital gain and may owe tax. However, borrowing against those same shares ordinarily creates loan proceeds rather than taxable income, because borrowed money must eventually be repaid.
Consider someone who owns $5 billion in shares purchased for a fraction of their present value. Selling $100 million worth could generate a substantial taxable gain, depending on the cost basis and other applicable rules. Alternatively, the owner might pledge shares as collateral and borrow $100 million from a financial institution. That arrangement provides liquidity without immediately realizing the appreciation embedded in the shares.
The borrower must pay interest, maintain sufficient collateral, and eventually repay or refinance the debt. Those obligations make borrowing economically different from selling assets, and the strategy is not costless. Nevertheless, someone with extensive appreciated holdings may be able to finance personal consumption while continuing to benefit from future asset growth.
This mechanism is often described as buy, borrow, die. The investor acquires appreciating assets, borrows against them during life, and retains them until death. Under the American stepped-up-basis rules, many inherited assets receive a new tax basis reflecting their value at death, potentially eliminating income taxation on appreciation accumulated during the deceased owner’s lifetime.
For example, an investor might purchase shares for $10 million and hold them until they are worth $100 million. Selling during life could trigger tax on a substantial capital gain. If the investor instead borrows against the shares and dies while still owning them, heirs may receive a stepped-up basis, subject to the relevant legal conditions. The outstanding debt still matters, and estate taxes may apply separately, but the built-in income-tax gain can disappear.
Public-company founders and other major shareholders have used arrangements involving pledged shares and secured borrowing. Such pledges are not, however, proof that the entire collateral value has been borrowed or spent. A filing showing billions of dollars in pledged stock does not establish an equivalent amount of outstanding personal loans.
The tax-policy problem is the unequal treatment of two ways to obtain liquidity from appreciated assets. A shareholder who sells may owe capital-gains tax immediately, while another who borrows against similar assets may defer that tax for years. Borrowing can therefore become attractive partly because of tax rules rather than because additional leverage is economically necessary.
The Yale Budget Lab’s analysis of buy-borrow-die reform examines three approaches. One would treat certain borrowing as a deemed realization event, another would require a prepayment of capital-gains tax when borrowing occurs, and a third would impose an excise tax on specified loans. Depending on the design, the researchers estimated federal revenue increases of approximately $102 billion to $147 billion over ten years.
These alternatives target an identifiable transaction rather than attempting to value every asset a billionaire owns. The loan amount, lender, collateral, and relevant borrowing arrangements can potentially be documented, making parts of administration more concrete. Because the borrower has received cash, liquidity concerns are also different from those created by an annual wealth tax.
None of the proposed reforms is effortless. Governments would need rules for ordinary business borrowing, refinancing, margin loans, changes in collateral value, and transactions undertaken for legitimate investment purposes. Poorly designed provisions could tax people who are borrowing for reasons unrelated to capital-gains avoidance or create problems when the same gain is eventually realized.
The strongest argument for reform is therefore not that wealthy people should pay income tax on every loan. It is that loans used to extract purchasing power from substantially appreciated assets can create tax advantages worth examining. Carefully narrowing that advantage could improve the treatment of economic gains without imposing a comprehensive levy on net wealth.
Inheritance Taxes, Estate Loopholes and Dynasty Trusts
If taxing wealth during someone’s lifetime creates difficult incentives, taxing its transfer between generations raises a different set of questions. An entrepreneur may argue that substantial taxes on accumulating wealth discourage risk-taking and business formation. That argument is less straightforward when the issue is whether descendants should inherit enormous fortunes without meaningful taxation.
Inherited wealth can support productive businesses, finance new ventures, and provide financial security. But it also gives recipients advantages unrelated to their own effort or ability. Extensive inheritance can reinforce inequality of opportunity, concentrate economic power, and allow certain families to maintain exceptional financial advantages over generations.
The OECD’s research on inheritance taxation examines how estate, inheritance, and gift taxes can contribute to redistribution, revenue collection, and equality of opportunity. It also recognizes concerns about family businesses, liquidity, avoidance, and administrative design. The appropriate treatment depends on the size and nature of the transfer rather than an assumption that every inheritance is economically harmful.
The United States already imposes a federal estate tax, although the terminology matters. An estate tax generally applies to the taxable estate of a deceased person, while an inheritance tax is typically imposed on beneficiaries receiving property. In 2026, the IRS federal estate-tax rules provide a basic exclusion of $15 million per individual, with married couples potentially benefiting from portability and other applicable provisions. The top federal estate-tax rate remains 40%.
Those headline figures suggest that exceptionally large estates should face substantial taxation. But taxable estates are not always equal to the market value of everything a wealthy family has controlled during its lifetime. Gifts, charitable transfers, trusts, ownership entities, and valuation rules can influence how much remains subject to estate taxation.
One widely used planning technique involves grantor trusts, under which certain assets and tax responsibilities are treated differently for income-tax and estate-planning purposes. Grantor retained annuity trusts, or GRATs, can transfer future appreciation under particular arrangements. Family limited partnerships and related entities may qualify for valuation discounts reflecting restrictions on ownership or marketability.
These mechanisms are not automatically abusive or illegal. There are legitimate reasons to organize family enterprises, make gifts, and plan for succession. Nevertheless, combinations of legal structures can produce substantial tax advantages, especially for families able to obtain sophisticated long-term advice.
Dynasty trusts take the intergenerational question further. Depending on governing state law and the trust’s design, assets can remain within a long-lived structure benefiting descendants over multiple generations. When combined with appropriate transfer-tax planning, such arrangements may reduce the frequency or extent to which accumulated wealth becomes subject to estate or generation-skipping taxation.
That creates an asymmetry between people who accumulate savings through wages and those who inherit assets inside sophisticated structures. Employees generally cannot avoid payroll or income taxation simply by placing their salaries into a multigenerational legal arrangement. Wealthy families, by contrast, may have far greater flexibility over the timing and taxation of transfers.
Reform could therefore focus on valuation discounts, grantor-trust treatment, generation-skipping provisions, and the tax consequences of inherited appreciated assets. Restricting particular avoidance opportunities may make existing estate taxes more effective without necessarily imposing new annual taxes on business ownership.
Still, policymakers must consider family-owned businesses with genuine liquidity constraints, the effects of inheritance taxation on saving and investment, and the possibility of avoidance through lifetime transfers. The objective should not be to eliminate the ability to provide for children or preserve productive enterprises. It should be to prevent tax preferences from allowing extraordinary inherited advantages to compound indefinitely beyond the reach of a reasonably fair tax system.
Why Carried Interest Is Taxed Differently
The carried-interest controversy concerns a different kind of advantage: income earned by investment managers that can receive preferential capital-gains treatment. Unlike an annual wealth tax, reforming this area would not require the government to assess a billionaire’s entire fortune. It would involve reconsidering how a particular form of investment-management compensation is classified.
Private equity and venture capital funds are frequently described using a 2 and 20 compensation model, although actual arrangements vary. The manager receives an annual management fee, often illustrated as 2% of committed or managed capital, together with a share of investment profits, commonly around 20%. Management fees are generally treated as ordinary business income, while qualifying carried-interest gains may be taxed at preferential long-term capital-gains rates.
Imagine a fund that raises $1 billion from investors. A simple 2% management fee would generate $20 million annually before expenses and other adjustments. If the fund eventually increased its investment value from $1 billion to $3 billion, it would have generated a hypothetical $2 billion profit. A 20% carried-interest allocation could then represent $400 million for the manager, subject to the fund’s actual distribution rules, hurdles, and contractual arrangements.
The controversy arises because this $400 million may represent compensation for investment-management services, yet qualifying gains can receive different tax treatment from ordinary wages or professional fees. The Tax Policy Center’s explanation of carried interest describes that distinction and the arguments surrounding it.
Supporters of preferential treatment contend that carried interest aligns managers’ incentives with investor returns and compensates them for taking risks. Fund managers may wait years before receiving profits, and performance-based compensation can encourage disciplined investment decisions. These characteristics distinguish carried interest from a guaranteed salary.
Critics respond that the investors generally provide most of the capital, while managers provide expertise, judgment, and services. From that perspective, much of the compensation resembles professional income, even when its amount depends on investment performance. Treating it more favorably than other high-income labor raises a legitimate question about tax neutrality.
American law already contains restrictions, including special holding-period requirements for certain carried-interest gains. But those provisions do not eliminate the broader distinction between compensation treated as ordinary income and gains eligible for preferential treatment.
Taxing carried interest more consistently as ordinary income would raise additional revenue, although not on the enormous scale sometimes suggested. The Congressional Budget Office estimate cited by the Tax Policy Center indicates approximately $13 billion over ten years for the relevant reform, rather than a guaranteed multibillion-dollar windfall every year.
The significance of the issue extends beyond the revenue estimate. A tax system becomes harder to defend when economically similar forms of compensation receive very different treatment because one can be structured through an investment partnership. Narrowing that distinction could improve fairness and credibility without requiring a new comprehensive wealth tax.
Does America Actually Collect Too Little Tax?
The debate over billionaire taxation raises a broader fiscal question: does the United States need additional tax revenue, or is the more important problem how existing revenue is used? Answering that question requires distinguishing several measurements that are frequently treated as interchangeable.
The United States collects an enormous amount of tax revenue in absolute terms. Its economy is the largest among OECD member countries, so large collections are unsurprising. Comparing total dollars collected by America and a much smaller country reveals little about the relative tax burden or the resources available to government.
Tax revenue per person offers another perspective, but it is influenced by income and economic productivity. A wealthy country may collect more tax per resident even with comparatively modest tax rates. Conversely, a lower-income country may impose substantial statutory rates yet collect less revenue per person because the underlying economic base is smaller.
Tax revenue as a percentage of GDP provides a different comparison. According to the OECD’s Revenue Statistics 2025 report, American tax revenue amounted to approximately 25.6% of GDP in 2024, compared with an OECD average of 34.1%. This suggests that the United States collects a smaller share of its national economic output in taxes than many other developed economies.
Importantly, the OECD’s standardized figures include compulsory social security contributions within their definition of total tax revenue. It would therefore be incorrect to treat American Social Security contributions as an additional amount that must simply be placed on top of the OECD comparison. Private insurance premiums and other household expenses raise different questions and cannot automatically be classified as taxes.
America also differs from many European countries in its tax composition. Federal personal income taxes play a major role in government revenue, while many OECD countries rely more heavily on value-added taxes and other consumption taxes. State and local property taxes are also relatively important in the American system.
These differences matter for distributional fairness. Broad consumption taxes can impose a larger burden relative to income on poorer households, although exemptions, reduced rates, and transfers can offset some effects. Income taxes can be designed progressively, while property taxes may influence housing decisions, local public services, and ownership costs.
No single tax structure guarantees superior economic performance. High income-tax rates may influence work, saving, avoidance, and investment, while low taxes can create revenue constraints or shift the burden onto other taxpayers. Property taxation may discourage particular investments depending on its design, although recurring land-value taxation has different economic characteristics from taxing improvements.
The Laffer curve is often invoked in these discussions. It illustrates the theoretical relationship between tax rates and tax revenue, including the possibility that sufficiently high rates reduce the taxable activity or compliance needed to sustain collections. But it does not establish where any particular country sits on that relationship, nor does it demonstrate that increasing American taxes would necessarily reduce GDP or government revenue.
The evidence therefore does not support the simple conclusion that America already collects so much money that additional taxation cannot help. Nor does it establish that raising tax rates will automatically produce better economic outcomes. Revenue adequacy depends on spending obligations, economic capacity, the distribution of tax burdens, and the government’s ability to collect taxes efficiently.
A well-designed reform can be worthwhile even when its revenue contribution is relatively modest. Reducing preferential treatment for particular transactions may improve fairness and reduce distortions independently of whether the government needs a dramatic increase in overall receipts.
Why More Tax Revenue Does Not Guarantee Better Public Services
Fair taxation and effective public spending are related, but they are not the same problem. A government can collect substantial revenue while delivering disappointing services, just as it can administer certain programs efficiently while lacking the money to meet legitimate public needs. Improving one side of the equation does not automatically resolve weaknesses on the other.
American healthcare offers a striking example. The Centers for Medicare & Medicaid Services’ national expenditure data show that healthcare spending reached approximately $5.3 trillion in 2024, accounting for about 18% of GDP. This is an extraordinary commitment of economic resources, particularly when compared with other wealthy countries.
High spending is not inherently undesirable if it produces commensurate benefits. The United States has exceptional medical research institutions, sophisticated hospitals, advanced treatment capabilities, and important pharmaceutical innovations. Yet overall health outcomes, affordability, insurance coverage, and access to care often compare unfavorably with those of other developed countries spending considerably less.
The explanation involves more than public funding levels. Insurance fragmentation, administrative expenses, complex billing systems, hospital market concentration, pharmaceutical prices, and inconsistent incentives can all raise costs. These structural weaknesses in the American healthcare system mean that additional money does not necessarily purchase proportionately better care.
International comparisons suggest substantial potential for improvement, but they should not be converted into a guarantee that trillions of dollars could immediately be saved. Differences in population health, wages, insurance arrangements, public institutions, and political feasibility matter. Reforming healthcare spending requires changing incentives, prices, administration, and service delivery rather than merely imposing lower budget limits.
Defense expenditure raises another accountability problem. The United States allocates enormous resources to its military, yet the Department of Defense has repeatedly failed to obtain a clean, department-wide financial statement audit. This reveals significant weaknesses in financial management, recordkeeping, asset accounting, and internal controls.
An unsuccessful audit is serious, but it is not equivalent to proving that all poorly documented expenditures were stolen or wasted. Audit findings identify problems in the reliability and verification of financial information. Addressing those weaknesses is essential for accountability, irrespective of whether policymakers ultimately choose higher or lower defense spending.
Federal improper payments present a similarly important distinction. The Government Accountability Office’s assessment of fiscal year 2024 improper payments reported approximately $162 billion in improper federal payments, compared with roughly $236 billion in fiscal year 2023. These are substantial figures that justify concern about the quality of public financial administration.
However, improper payments are not synonymous with fraud. They may include overpayments, underpayments, payments made without sufficient documentation, and other administrative errors. Some involve deliberate deception, while others reflect weaknesses in eligibility checks, reporting systems, or program administration. Treating the entire amount as stolen money would misrepresent the evidence.
Waste, inefficient procurement, administrative duplication, weak program design, and insufficient oversight can all undermine the value taxpayers receive. Governments therefore need mechanisms for evaluating outcomes, detecting improper expenditure, improving financial controls, and correcting policies that are not delivering their intended results.
Nevertheless, the existence of spending problems does not make tax reform unnecessary. Insufficient revenue can also undermine healthcare, infrastructure, public safety, education, and other essential services. A government that improves efficiency but lacks adequate resources may remain unable to fulfill its obligations.
The sensible objective is to improve both sides simultaneously. Governments should collect revenue through transparent, enforceable, economically defensible rules while ensuring that spending produces measurable public value. Better taxation and better public administration reinforce each other because taxpayers are more likely to view a system as legitimate when its obligations are fairly distributed and its benefits are visible.
The central question is therefore not simply whether the government can collect another $100 billion. It is whether that money represents a sustainable increase in public resources and whether the institutions receiving it can convert those resources into meaningful improvements.
The wealth-tax debate often begins with a moral argument about fairness, and that argument deserves to be taken seriously. Extraordinary private fortunes exist alongside significant public needs, while much of the modern tax system depends on definitions of income and realization that do not always capture the full economic advantages enjoyed by the wealthiest households.
But fairness must be translated into rules that actually work. Wealth taxes may have a legitimate role, particularly where valuations, enforcement, and institutional arrangements make them practical. Their difficulties are substantial, however, and the experiences of different countries show why neither automatic rejection nor unquestioning enthusiasm is justified.
Taxing certain borrowing arrangements, strengthening estate taxation, limiting dynastic loopholes, and reforming carried-interest treatment offer additional ways to address specific advantages. Each approach has costs and trade-offs, but each also targets an identifiable weakness in the existing system rather than relying exclusively on a broad assessment of total wealth.
Ultimately, effective tax policy requires more than finding wealthy people from whom money can be collected. It requires designing rules that remain enforceable when taxpayers respond, preserving productive economic incentives, and ensuring that additional public resources are used well. The goal should be a tax system in which extraordinary wealth cannot routinely escape fair taxation—and a government capable of demonstrating what society receives in return.
