Do…people really think that prices will go down when cheap foreign labor is off the table? Do they think we can establish replacement infrastructure at comparable costs in months or a couple of years? Will they want to work those jobs for comparable pay to keep the costs of goods stable?
Probably more like wages will go up when cheap foreign labor is off the table. Higher income offsets higher prices for industries where wages rise. For the currently well paid the purchasing power may drop.
Silicon Valley didn't care about the rust belt, so why should the rust belt care about SV?
The fallacy here is that US industries will even be able to compete with 200% tariffs.
They won't, and they can't, and they certainly can't do it immediately. It takes decades to build up the manufacturing efficiency and processes to compete with China. We lost all of it.
We will continue to buy from China because it will STILL be cheaper. And your goods will be 3x more expensive, and that's the best-case scenario for a lot of goods.
