My thought today was that aside from the stocks crashing, and aside from any realistic possibility of magically minting new manufacturing facilities, you'd force the price of imported products up in the short term, and prices don't really go back down, so after they go away you'll hypothetically be selling the same products at higher prices that people are now used to, and nothing else needs to happen functionally to increase efficiency or build them domestically. 1) Increase cost of selling imports 2) Crash stock market 3) Buy stocks 4) Remove tariffs 5) Profit

But I don't know wtf I'm talking about.
