Summary

Thomas Sowell transitioned from being a committed Marxist to a classical liberal after working in government and discovering that policy decisions are driven by institutional incentives rather than evidence or truth. His pivotal moment came at the Department of Labor when colleagues resisted investigating whether minimum wage laws were causing Puerto Rican unemployment, revealing that government agencies prioritize self-preservation over data-driven policy.

    Thomas Sowell was once a committed Marxist. Even after Harvard. Even after Milton Friedman. So what changed his mind? It wasn’t a book. It was working in government. Here’s the story 🧵

  2. #2

    In his twenties, Sowell was all in on Marxism. He read deeply. Argued fiercely. Bought encyclopedias to understand class theory. By the time he got to Harvard, classmates called him “the Marxist guy.” He believed it—not casually, but seriously.

  3. #3

    Back then, Sowell worked as a messenger in New York City. His commute took him from Harlem to Manhattan— From the poorest neighborhoods to the wealthiest skyscrapers. Day after day, he asked: Why does this economic disparity exist?

  4. #4

    Marxism offered an answer. Oppression. Exploitation. Capital vs. labor. It felt coherent. Even moral. So he dug deeper—through books, theory, and debates. It didn’t feel radical. It felt like truth.

  5. #5

    He earned his master’s at Columbia. Took classes with Milton Friedman at the University of Chicago. Still a Marxist. That didn’t change—until he saw how government actually works.

  6. #6

    At the U.S. Department of Labor, Sowell was tasked with studying minimum wage laws in Puerto Rico. The key question: Why was unemployment rising? Two possibilities: 1. Minimum wage laws were killing jobs 2. Hurricanes had ruined the harvest

  7. #7

    Sowell had a simple idea: test it. If the plantations were still standing after the hurricane, it wasn’t the weather. It was the law. He didn’t need ideology. He needed data.

  8. #8

    He brought the idea to his team. And that’s when it hit him. They weren’t curious. They were nervous. Because if minimum wage laws hurt the poor—the Department of Labor might be the problem. And no one wanted to say that.

  9. #9

    That was the moment. The moment Sowell realized: Government isn’t driven by truth. Or data. Or public good. It’s driven by its own incentives. That’s when the Marxist cracked. And the classical liberal emerged.

  10. #10

    He never got the crop data. But he got something better: A real-world education in incentives, bureaucracy, and political self-interest. And he’s spent a lifetime explaining it to the rest of us.
