If President Donald Trump goes through with his plan to levy sweeping tariffs on foreign imports, it wouldn’t be the first time the U.S. has done such a thing. Ever heard of the Smoot-Hawley Tariff Act of 1930? Anyone? Those tariffs are widely credited with sinking the United States deeper into the Great Depression.

On the show today, Inu Manak, a fellow for trade policy at the Council on Foreign Relations, explains how the Smoot-Hawley tariff debacle can shed light on the current moment, why the president has the power to wield tariffs in the first place, and how punishing trading partners could leave the U.S. economy at a disadvantage. Plus, what this fight has to do with the 1980s film “Ferris Bueller’s Day Off” and Roomba vacuum cleaners!
