Let's not be hyperbolic. The US is still the second largest manufacturer in the world.

Small US companies near me, reliant on Chinese inputs, aren't suddenly getting hundreds of millions to build factories that'll take years to finish. Trump’s plan assumes most small businesses can pause everything for long, expensive factory construction/toolup projects. In my area our three big manufacturers depend on Canadian aluminum and Chinese subcomponents. Tariffs won’t bring jobs back but they’ll kill the ones we still have.

That's maybe the biggest problem with the Trump tariffs - not enough time to adjust. If you were doing it properly you'd plan years ahead.

Which is likely one reason among many why Biden didn't cancel the Trump v1 tariffs. Instead the IRA included a good chunk of money to invest in green infrastructure. We had Trump sticks and Biden carrots working somewhat harmoniously, and a smooth transition.
