The idea that somehow US tariffs will force american oligarchs to spin up semiconductor companies and invest in medical technology is ridiculous.

Capitalists abandoned the nation fifty years ago. They were given monopolies and levity to crush organized labor at will. It may be the US international and domestic security policy to become independent of the communist nation of the PRC, but this just won't happen. Chicken tax style loopholes and other bureaucratic work will sidestep any national efforts to curtail capitalism's ability to sell out the country for profit.
