The Tax Pitch That Could Spell The ‘End Of America’

United Airlines CEO Scott Kirby opened a door this week that most corporate titans keep sealed: he called for a national wealth tax during a CNBC appearance, and went further by endorsing inheritance taxes approaching 100% on certain estates. Kirby didn't frame it as class warfare—he positioned it as a remedy for inequality that's reached levels he views as destabilizing. The specific mechanics matter here: a wealth tax would target accumulated assets annually, not income, hitting net worth above some threshold. Inheritance taxes near 100% would essentially confiscate estates above that level, preventing dynastic wealth transfer. These aren't theoretical proposals—Vermont Senator Bernie Sanders has introduced wealth tax legislation multiple times, and similar frameworks operate in parts of Europe, though most have since abandoned them after capital flight and administrative collapse.

What's genuinely at stake is the foundation of capital accumulation itself. A wealth tax fundamentally changes the math on long-term investment and asset building. If you own a $50 million business and face a 2-3% annual wealth tax, you're paying $1-1.5 million annually on top of income taxes, property taxes, and corporate taxes. Over two decades, that math forces asset sales just to meet the tax bill—meaning founders lose voting control of companies they built, family enterprises get liquidated, and capital allocation decisions move from owners to tax collectors and administrators. For anyone with significant real estate, equities, or operating businesses, this isn't abstract: it's the difference between passing a going concern to your children versus forced fire sales. Kirby's airline has roughly $25 billion in assets; under a wealth tax regime, he'd face pressure to downsize or distribute capital differently, affecting investment capacity and potentially pricing and route decisions that ripple through the entire industry.

The historical precedent is instructive and grim. France implemented a wealth tax in 1989 with similar equality-focused rhetoric. By 2017, the tax had pushed out roughly 42,000 millionaires and generated only 5.4 billion euros in revenue—roughly 0.3% of total tax revenue—while costing the treasury far more in capital flight and reduced economic growth. Wealthy individuals and their assets moved to Belgium, Switzerland, and Luxembourg. French policymakers eventually repealed it, replacing it with a real estate-only tax that captured fewer exit routes. The lesson: wealth taxes look good on paper but require either comprehensive global coordination (impossible) or acceptance of massive capital emigration (expensive). The U.S. has additional complications—Americans can renounce citizenship, but face exit taxes; foreign-held assets are harder to track; and venture capital, which funds startups, becomes scarcer when founders know they'll hemorrhage wealth annually regardless of profitability.

The conservative read here is straightforward: Kirby is essentially endorsing confiscation. A 100% inheritance tax isn't taxation; it's the state claiming that no American can build something for their children. It's the logical endpoint of treating wealth as inherently illegitimate rather than the result of value creation. Kirby's own $250 million net worth exists because someone—airline founders, investors, workers who chose to work for United—valued what he built enough to pay for it. Endorsing 100% inheritance taxes means endorsing the principle that the moment Kirby dies, whatever he accumulated reverts to the government regardless of his wishes or his family's interests. That's not a tax policy; it's confiscation dressed in equity language. The wealth tax piece is worse in some ways because it's recurrent—it taxes the same dollar multiple times and forces asset sales during downturns when valuations are lowest. If the market drops 40%, your wealth shrinks but the 2% tax on nominal value still comes due. You sell into a falling market to pay taxes on unrealized losses.

What to watch: Sanders has reintroduced the Billionaire Income Tax in the current Congress with co-sponsor Elizabeth Warren. It's currently in committee and has zero Republican support and lukewarm Democratic backing—but the fact that a sitting CEO is now publicly championing it changes the political calculus. If even a handful of business leaders follow Kirby's lead,
