If we look at the history of how US dismantled its manufacturing after the 90s (yes it started way before, but it was in much smaller scope), it was WALL STREET manipulation that allowed jobs to escape to countries with lowest amount of human rights but cheapest wages. You see before then, companies did offshoring but it was in small quantities, because they feared the unions and especially the massive import tariffs that would have been thrusted on them by the government if they had gone mostly offshore.

NAFTA, which was heavily pushed by wall street and also welcomed by certain corporations, snuck in through NAFTA-friendly advisors that Clinton surrounded himself with. By establishing the principle that U.S. corporations could relocate production elsewhere and sell back into the United States, NAFTA undercut the bargaining power of American workers. Also by letting China into WTO in the 90s, China has been abusing the rules ever since, destroying manufacturing jobs in democratic countries around the world. Bush escalated the suffering by giving China most preferred status. Obama didn't do much to contest except some stern warnings against China.

And now we have a belligerent China, lead by a dictator, that is more powerful than USSR in its heydays, with signs of third-reich behaviors (muslim concentration camps, technology-thought controls), vastly increasing its military and technological weapons to confront and attack US and its allies. And technology companies are still transferring technologies to China, either willingly, unwillingly or unknowingly.

WALL STREET did this. Some corporations were complicit. Then most of them were. Bill Clinton destroyed the American workers. Every other presidents that followed didn't stand up. Trump actually confronted China.

And now WALL STREET is trying to stop the full $600B trade tariffs against China.
