Big capitalists in the US do not affirm any political party.

What they affirm is capital gains (not like the state owned enterprises in china). Capital has no nationality. If production doesn't happen in china, it will move to india, argentina, brazil, or vietnam etc. If most goods were produced domestically in the US, the majority of Americans would no longer be able to afford them. No other countries would buy from us. The real solution is to diversify global supply chains while keeping the most critical manufacturing capabilities onshore.
