Those companies that left were going to leave regardless. Buh bye. They like less productive workers more.Sure they are better off. It's us who suffer as our dependency on foreign made products increase. Don't you remember covid? All our PPE was made in China, and they're not about to take care of us first.
Of course we can't work for Chinese wages, but other factors are considered such as transportation costs and manufacturing close to your customer base. When the cost of making products here exceed the costs of making products overseas including shipping and warehousing, those products are then moved overseas.
So tell me, if everything we buy were made in China or another country, where would we Americans work?
