Myths That Built Trickle-Down Economics: Zombie Economics (with Paul Krugman)

This week, we’re continuing our archive miniseries, Myths That Built Trickle-Down Economics, with the myth that bad economic ideas die once the evidence proves them wrong.

They don’t. They come back as zombie ideas: tax cuts for the rich sold as growth policy, safety-net cuts sold as responsibility, and market fundamentalism sold as common sense. These ideas have failed again and again, but they keep returning because they still serve the people and institutions with the most power.

In this episode, Nobel Prize-winning economist Paul Krugman joins Nick and Goldy to explain why zombie economics refuses to die, how bad assumptions infected mainstream economic thinking, and why defeating trickle-down economics requires more than better evidence — it requires naming the myths that keep shaping our politics.

This episode originally aired on March 31, 2020.

Paul Krugman is a Nobel Prize-winning economist, professor, author, and former New York Times columnist. His book Arguing with Zombies: Economics, Politics, and the Fight for a Better Future examines the failed economic ideas that continue to dominate American policy debates.
