Actually US businesses were doing fine for the most part, except for those trying, and failing, to compete with the ladder replacements that moved overseas. There is a militarily strategic reason for keeping domestic production of your full supply chain, but most businesses don't care because (and this is a shocker) corporations aren't Americans, nor are they Chinese or any other nationality. They are greedy and self-interested and don't give a hoot about their country of residence.
Caring about the market, and not societies, is the kind of capitalism, that the US has been heavily promoting for quite a while. But seems like young people are starting to catch on to this social-democracy thing..
