Why Tariffs Can't Rebuild American Manufacturing | The Professor Is In

Why did Trump's tariffs fail? It's a competence problem, not just a trade-theory problem.
Economist Justin Wolfers answers your questions about why the Trump administration's tariffs earned straight F's on their own stated goals. His argument: the problem isn't only the economics of tariffs — it's chaotic, incoherent implementation. When a policy exists on Monday, is gone by Tuesday, and gets thrown out by a court on Thursday, you'd be crazy to build a 50-year factory around it. Across-the-board tariffs give you no leverage over China, targeting friendly Canada over fentanyl sets no clear incentives, and skipping Congress means the next president erases the whole thing with a pen. Justin warns the real lesson isn't "tariffs don't work" — it's that incompetent tariffs don't.
This is happening to you: two-to-one, Americans oppose these tariffs, and the higher prices land in your grocery cart and your next big purchase, not on foreigners. Justin also pushes back on "manufacturing fetishism" — arguing that what you actually want for your kids may be a keyboard, not steel-toed boots — and closes on why AI, unlike past economic shifts, may hit knowledge workers like you fast enough to really sting.
