Sep 25, 2026 · 30m

Summary

This episode explores the "stealthy wealthy," a class of three million multimillionaires who collectively hold 13 times the wealth of the Forbes 400. Economist Eric Zwick and his team, the "Tax Ninjas," used IRS data to reveal that pass-through businesses, not just tech giants, drive U.S. inequality. The show traces their rise to the 1986 Tax Reform Act and highlights how these "Middle Garchs" wield political power to shape regulations, from car sales to dental services.
