Of all the arguments for protectionism, the infant industry argument probably has the strongest theoretical appeal. By protecting a new industry from its more developed foreign competition, the story goes, tariffs give domestic producers the time to grow, learn, and become efficient enough to stand on their own. Domestic consumers feel the short-term pains of higher prices, but they enjoy the long-term gains of job growth and lower prices as the new industry blossoms.
It's no secret that tariffs have driven significant price increases over the last year and a half. A study from the New York Federal Reserve finds that tariffs "contributed 2.9 percentage points to goods price inflation" and that without tariffs those prices would have slightly declined. Tariff defenders, looking for a new reason to claim these higher prices are only temporary, have reimagined the infant industry argument. Now it's being used to support trade barriers in industries that are over a century old, but the promise is exactly the same: Domestic firms need the protection so they can compete, innovate, and cut costs until prices come back down even further than they were before the tariffs.
