That can only happen if you ban all imports of anything those small business manufacturers would made, and be content with the prices going up so those Americans can really be paid who make those products.
If that is not possible, then it is either slavery, poorly paid illegal immigrants or back to some other low-wage country like we’ve done for the past decades.
Counterpoint: About 1/3 of Australia's GDP is small business. We have very few tariffs. We have a high minimum wage (about USD$16/hr) and it's enforced, so slavery yada, yada isn't a factor.
What you said sounds like it might be true, but in reality it ain't so.
Consumers could always make this decision for themselves and pick domestic over foreign. It seems extremely unlikely, but I also see bringing back manufacturing without massive economic shock as extremely unlikely. If I want a pipe dream, it be for manufacturing to come back because consumers actually care that it comes back.
In a free market, consumers _do_ decide for themselves. It is simply so, that price is the primary factor for many consumers. Especially in a society where living paycheck to paycheck is normal - but really in any society.
