When the next recession hits, the layoffs will occur. After things start getting better, the jobs will not return.
Yeah the jobs not returning has been going on for quite a while. Once upon of time, I was employed in the textile industry (warehouse rather than production). Even in just the two years or so that I worked there, the company was shutting down mills and moving production to Asia. They eventually got bought out by a Japanese zaibatsu and now are nothing but a branding logo (The Munsingwear penguin lives on).
Even if massive tariffs were imposed, reviving textile production in the U.S., those jobs would not come back.
