While it's nice to buy American, it's about impossible. The entire world economy is intertwined. You may buy a Nissan, made in Mexico, with steel from the US, paint from Canada and parts from who knows where. We want good US jobs from American companies. But, most huge corporations are global in nature. For example, 3M manufactures in the US, Europe, South American, Asia, etc. They started as a US company, but they are really international.
We're happy when foreign companies provide jobs in the US, ie Bayer, Mercedes, Nestle, and so on. I think the bigger issue is that countries like China do not trade fairly, and it would be good if the US, European Union, Australia and some others took a hard line with them where possible. They manipulate their currency, steal intellectual property, counterfeit products, disallow outside investment and abuse human rights. I am disgusted by companies like Apple and Nike that grind labor down to peanuts in Asian countries while profiting wildly on overpriced products. You can blame the investor class for their lust for returns with little regard for human costs. Apple would still be very profitable operating and manufacturing in the US.
We export meat to China? Yeah, Smithfield foods is owned by the Chinese. This is not easy.
