As everyday Americans navigate a stubbornly high cost of living and mounting pressure from inflation, a familiar debate over economic disparity has taken an unexpected turn. Corporate leaders rarely advocate for policies that directly target the fortunes of the ultra-rich, but United Airlines CEO Scott Kirby is breaking ranks. In a candid interview, the chief executive called for sweeping federal reforms, proposing a national wealth tax and inheritance levies that could approach 100% for high-net-worth individuals at a certain threshold.

Speaking with The New York Times, Kirby addressed the broader issue of declining public trust in corporate executives and corporate America at large. He pointed directly to the growing chasm between affluent households and the rest of the population as a systemic threat to societal stability.

"Wealth inequality has become a danger to our society, and we need to address that," Kirby told the publication. "We should have a national wealth tax — it won’t work by state because people will just move. And I think we should have inheritance taxes that get close to 100 percent at some level. I would pay them."

Kirby, whose personal net worth is reportedly valued at over $125 million, did not outline a comprehensive legislative roadmap or detailed administrative framework for how such sweeping tax policies would be implemented. However, his remarks immediately injected new life into the national conversation surrounding tax fairness, corporate responsibility, and the concentration of capital in the United States.

The timing of Kirby’s comments aligns with stark economic data regarding the American wealth gap. According to reports from the Center for American Progress, the wealth gap in the United States has reached its widest point in three decades. Current figures indicate that the top 1% of households hold nearly 32% of the nation’s total wealth, translating to roughly $55 trillion in assets. By contrast, the bottom 50% of the population collectively holds only about 2.5% of total U.S. wealth.

To evaluate the feasibility and implications of Kirby’s proposals, financial analysts and tax policy experts point to how the existing U.S. tax system operates.

Types of Income the IRS Taxes

Under the current tax code, the Internal Revenue Service levies taxes on various streams of income, including traditional wages, salaries, business earnings, and certain realized investment gains. However, the federal tax system generally does not tax accumulated wealth—the sheer volume of assets an individual builds up over time unless those assets generate taxable income or are transferred under specific circumstances.

The federal government does, nevertheless, levy taxes on wealth transferred after a person’s death. When applicable, the estate itself—rather than the individual heir—is generally responsible for paying the federal estate tax, which carries a maximum statutory rate of 40%. Despite this top rate, the federal system includes a historically high exemption threshold, meaning that the vast majority of American estates owe zero federal estate tax upon the owner’s passing.

For individuals dying in 2026, the federal lifetime estate tax exemption stands at $15 million per individual, or $30 million for married couples filing jointly. Beyond federal parameters, individual states maintain independent tax structures. Five states—Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania—levy specific taxes on inheritances received by beneficiaries, complete with their own distinct rules and exemption limits.

The broader takeaway for taxpayers is that inheriting money or property under current federal law does not automatically trigger federal income or inheritance tax liability. The final tax outcome depends heavily on the specific classification of the asset, the overarching circumstances of the estate, and the state laws governing the transaction.

What Would a Wealth Tax Change?

Implementing a national wealth tax would represent a fundamental departure from traditional American tax policy. Rather than taxing the income an individual earns within a specific calendar year, a wealth tax targets a person’s net worth—calculated as the total value of all assets minus outstanding debts at a given point in time.

For instance, consider an individual who owns $50 million in real estate, stocks, and business investments while carrying $5 million in various liabilities. Their net worth would total $45 million. Under a hypothetical wealth tax structured to apply to net worth exceeding $20 million, a portion of that accumulated wealth could be taxed annually, regardless of whether the asset holder earned significant income during that particular year.

Designing such a system, however, presents immense administrative hurdles. Lawmakers would need to resolve complex questions regarding which asset classes to include, how to accurately determine market valuations, what threshold should trigger the tax, and how frequently collections should occur. Valuing illiquid assets, such as private family businesses, commercial real estate, fine art, and rare collectibles that do not trade on public exchanges, would introduce significant logistical and legal challenges.

These debates are not merely theoretical. Voters in California are preparing to weigh in on similar policy questions at the ballot box, reflecting a growing appetite among certain lawmakers to explore targeted levies on high-net-worth individuals.

Proponents of the California measure argue that the revenue generated would be directed primarily toward funding critical public services, such as healthcare expansion, public education, and food assistance programs. Economic analysis and independent expert reports suggest that such temporary measures could yield tens of billions of dollars in revenue over a multi-year period.

Conversely, opponents of wealth-based taxes warn that aggressive levies could prompt wealthy residents and profitable corporations to relocate to more tax-friendly jurisdictions, ultimately weakening state finances over the long term. State-level fiscal analyses have previously attempted to model this potential "tax flight," suggesting that the migration of billionaires could impact income tax collections, though estimates of the net loss vary widely.

While the California proposal focuses on a temporary state-level tax on billionaires rather than a permanent recurring wealth tax, it underscores the structural complexities that federal lawmakers would encounter. These include navigating asset valuation disputes, determining jurisdictional reach, and closing loopholes designed to evade assessment. At the same time, numerous other state legislatures are actively debating adjustments to tax structures aimed at high-income earners, signaling a sustained political focus on economic disparity across the country.

The Difference Between Wealth Taxes and Inheritance Taxes

Discussions surrounding progressive tax reform often conflate distinct financial mechanisms. A wealth tax is designed to apply to the ongoing pool of assets an individual currently owns, while an inheritance tax is levied directly on the money or property an individual receives from someone who has died.

Furthermore, an inheritance tax operates differently from an estate tax. While an estate tax is assessed against the total estate before any distribution takes place, an inheritance tax is imposed on the recipient based on their individual share of the inheritance and their relationship to the deceased.

Advancing a policy that features tax rates approaching 100% on substantial inheritances—as suggested by the United Airlines chief executive—would mark a historic shift in U.S. fiscal policy. Supporters of heavier inheritance levies argue that curbing massive intergenerational wealth transfers is essential for preventing entrenched economic stratification and securing adequate funding for public infrastructure. Critics, however, contend that confiscatory tax rates would severely penalize family-owned businesses, farms, and multi-generational enterprises, often forcing heirs to liquidate core assets simply to satisfy the tax bill.

The ultimate impact of any such reform would hinge entirely on legislative specifics, including the magnitude of exemptions, the proposed rate structures, and the protections afforded to closely held businesses and productive capital. Furthermore, enacting a national wealth tax or massive inheritance overhaul faces formidable political hurdles, particularly in a closely divided Congress where bipartisan consensus on tax policy remains difficult to achieve.

What New Taxes Mean for Your Financial Plan

For the average American household, Scott Kirby’s public commentary does not alter the immediate tax landscape governing investments, savings, or future inheritances. Most families will never reach the high thresholds required to trigger federal estate or wealth-related liabilities.

Nevertheless, financial advisors emphasize the importance of monitoring state-level tax policies. Because several states maintain estate tax exemptions significantly lower than the federal limit—alongside distinct inheritance and death taxes—the geographic location of both the asset holder and the beneficiary can heavily influence the final wealth retained across generations.

As the national debate over economic inequality, corporate governance, and tax policy continues to evolve, financial planners recommend that individuals with complex estates consult qualified tax professionals to navigate changing rules and safeguard their long-term financial plans.
