On Derek Thompson’s Plain English podcast, he interviews Gabriel Zucman (Paris School of Economics, UC Berkeley) about the current state of the American tax system and on how a wealth tax might address some of the concerns raised. From the podcast’s summary:

If you’re a typical worker with a salary, you have almost no control over how much tax you owe. But if you own a company worth billions of dollars, the income tax is, in the words of my guest today, “largely optional.” Countries around the world struggle to get billionaires to pay a higher tax rate than middle-income families.

Gabriel Zucman is one of the world’s leading experts on tax inequality, the economist who first rigorously measured what U.S. billionaires actually pay—and he found that it’s less, as a share of income, than what a middle-class American pays. He’s advised Elizabeth Warren and Bernie Sanders on wealth tax proposals and recently published sweeping new research showing that the problem is global. Today, we get into the mechanics of billionaire tax avoidance, the history of failed wealth taxes, and whether the AI era is about to make all of this dramatically worse.
