Worst. Tariffs. Ever. (update)

Episode Summary

Executive Summary: Planet Money revisits Smoot-Hawley to explain why tariffs remain politically tempting but economically risky, connecting the 1930 collapse in trade to Trump’s first-term tariffs and his proposed second-term hikes. The episode argues tariffs often raise consumer prices, trigger retaliation, and harm downstream industries more than they help protected sectors.

Main Topics: Smoot-Hawley as economic cautionary tale (Priority: 5/5): The episode explains how the 1930 tariff bill became shorthand for policy disaster, using Doug Irwin’s research and the Ferris Bueller scene to show why it still matters. Why Congress created the tariff mess (Priority: 5/5): In 1928-1930, farmers sought protection, but logrolling in Congress expanded a narrow agricultural tariff into a sweeping bill affecting hundreds of industries. Economic harms of tariffs (Priority: 5/5): The show details downstream cost increases, consumer price pass-through, and foreign retaliation as core reasons economists oppose tariffs. Trump’s first-term tariffs and second-term promises (Priority: 4/5): The episode updates the historical story by comparing Smoot-Hawley to Trump’s steel, aluminum, and China tariffs, plus his proposed broader import taxes. Shift of tariff power from Congress to the presidency (Priority: 4/5): Smoot-Hawley helped lead Congress to delegate tariff authority to the executive branch, enabling modern presidents to act more directly on trade policy. Trade retaliation and global effects (Priority: 4/5): Using eggs, Canada, and global trade contraction as examples, the episode shows how tariffs spark countermeasures and wider trade disruption.

Key Arguments: Smoot-Hawley started as a farmer-protection bill but expanded through logrolling into a much larger and more damaging tariff package. Tariffs often hurt the same domestic industries they are meant to help by raising input costs for downstream producers and consumers. Countries retaliate against tariffs, reducing exports and escalating protectionism beyond the original policy. Economists warned Hoover against Smoot-Hawley, and those warnings proved largely correct after passage. Trump’s first-term tariffs did not meaningfully change China’s policies and were largely passed through to U.S. consumers. Congress later delegated tariff authority to the president partly because Smoot-Hawley showed lawmakers could not manage the process responsibly. Even targeted tariffs can create the same price and retaliation effects as broader ones, though broad across-the-board tariffs would be most Smoot-Hawley-like.

Data Points: Year of Smoot-Hawley passage: 1930 - The tariff bill discussed as the historical benchmark for harmful protectionism. Imported goods targeted in Trump first term: About $370 billion - Trump imposed tariffs on roughly this amount of imports from China by the end of his first term. Potential proposed tariff rates (second term): 20% baseline; 25% on Mexico and Canada; up to 60% on China - The episode cites Trump’s varying public tariff proposals for a second term. Economists warning Hoover: More than 1,000 economists - A large group signed a letter urging Hoover/Congress to stop Smoot-Hawley. Printed testimony: More than 8,000 pages - The Senate heard extensive testimony as industries lobbied for protection. Witness count: More than 1,000 witnesses - Industry groups flooded Congress during tariff deliberations. Number of tariff increases: Over 800 - The original narrow proposal expanded into hundreds of tariff changes. Egg export decline: From almost 1 million dozen to 13,000 dozen - U.S. egg exports to Canada collapsed after retaliation over egg tariffs. Canada egg tariff: From 3 cents to 10 cents per dozen - Canada retaliated against the U.S. egg tariff with an equivalent increase. U.S. egg tariff: From 8 cents to 10 cents per dozen - One example of a tariff adjustment under Smoot-Hawley. Global trade decline: 26% - World trade fell in the years after Smoot-Hawley amid tariffs and the Great Depression. Household tax impact estimate: $200 to $300 per household - Tax Foundation estimate for the Trump-Biden tariffs’ average burden on American households. GDP effect estimate: Down 0.2% in long-run GDP - Tax Foundation estimate of the broader economic drag from Trump-era tariffs.

Pivotal Quotes: "In 1930, the Republican-controlled House of Representatives passed the... The Hawley-Smoot Tariff Act" — Ben Stein clip / Ferris Bueller reference: Opening example used to show how Smoot-Hawley became a famous pop-culture economics lesson. "It did not work. And we lost jobs in downstream user industries, and it failed to revitalize the steel industry." — Doug Irwin: Irwin’s improvised summary of Trump’s 2018 steel and aluminum tariffs. "We have a huge number of facts here to lean on... the tariffs will be a disaster for the economy" — Narration summarizing economists’ letter: Describes the economists’ opposition to Smoot-Hawley before passage.

Implications: Tariffs remain politically attractive but usually act like hidden taxes on consumers and business supply chains. Broad tariffs risk retaliation, higher prices, and slower growth, making Smoot-Hawley a live warning for current policy debates.
