Gotta stop you right there: the tariffs come first, then YEARS LATER the manufacturing jobs come back home. In the interim the consumer is paying more without benefit of one of those sweet new American manufacturing jobs.
I've actually seen this play out in companies I've worked for as they shuttered manufacturing facilities overseas and brought some work back home. It takes a lot of time and a significant cost. ESPECIALLY if the goal is to bring back factory jobs which require years of work to set up, build, develop the infrastructure for.
So your plan will work, but it will take YEARS of pain for the American consumer. I kind of doubt that they have it in them to put up with it for very long (given how loudly they've complained about the recent cost spikes due to inflation).
My view is pragmatic. From having spent a few decades here in corporate American watching the sausage get made.
Honestly it is like you don't see that I agree with you in the desire to get our jobs back. But talking to you is not unlike having the same conversation with a 3rd grader who has no clue how all of this works.
I'm trying to tell you your dream, as laudible as it is, WILL cause problems. Problems a LOT bigger than you are giving them credit for being.
Let's say you were presenting an idea to the Board of Directors. If you haven't thought about the downsides an potential risks, you will be laughed out of the room very quickly.
