Except it won't shift. Sure some consumers and businesses might try to by USA made for a better price, but many products, and parts for products, are just not available in the USA. So US businesses, especially small business suffer, and maybe even go bankrupt. Sure Apple has a gazillion dollars and can move *some* production to the US, but they certainly aren't moving their iPhone production. It's too expensive for most businesses to retool and build manufacturing here, especially when it all might get reversed in ~3.5 years (or sooner).

That's probably true.
So yes import tariffs don't work, but they don't work because they squeeze the American consumer instead of squeezing the foreign producer.
I don't know where the idea comes from that you can squeeze producers especially from China. China doesn't make high margin goods, they have cutthroat competition on very ordinary products.
A $1000 champagne bottle from France might be different but that's not the bulk of the imports.
