China is not a typical country. It is huge, has its own market, and has a long history of isolation and self-containment.
America’s elites (encouraged by business cronies) 30 years ago thought that “open trade” would integrate China into the world / US dominated order of things. That’s not to say the US hasn’t got some benefits - cheap consumer goods allowed the government to issue massive debt, and our Federal Reserve to print money like crazy without fear of inflation. Once again - America’s elites skim the cream. Of course, it also suppressed wages for America’s middle class as well.
Politically, China has not behaved exactly as our elites planned. China used openness to its advantage and own growth to obtain jobs for its citizens, money for investment, and technology for itself.
If you notice, Schumer, Pelosi and the Democrat Party are not opposing Trump on this. I think the entire US establishment now understands the USA should not be contributing to the power of the Chinese Communist Party or helping raise-up a strategic rival.
Free Republic is not what it used to be.
