There probably isn't enough labour to onshore everything like you're implying.

The US currently consumes about half of its goods from domestic manufacturing. There are about 12 million people currently employed in manufacturing, and 7 million unemployed people. Matching the historical all-time low for unemployment rate would give around 4 million unemployed still.

> There is not, and never will be, a shortage of cleaners, for example, because anyone can do it, so as long as there are unemployed people and the wages are good enough, someone will do the work.

I mean, by that logic there's never a shortage of any profession. But in practice, I've seen what happens with a shortage of cleaners in a popular tourist town (my wife used to run a cleaning business) - it becomes nearly impossible to hire cleaners because everyone's salary in the area is inflated and people would rather work at an easier job. You run into persistent performance issues with your remaining cleaners - they're dishonest, simply stop showing up to work without notice, etc. You can't hire anyone from outside the area because there's no housing available other than dingy, overpriced basements. Holes get blown in the budgets of schools, hospitals, etc. because they have to contend with cleaning rates that are effectively set by the competitive market for cleaning AirBnBs.
