Nothing causes a company to scramble faster to keep their US production lines operational than tariffs. I've seen it in action.

And protecting US manufacturing is a serious national defense issue as far as I'm concerned. It is more than worth the sacrifices required to make it work.

Without tariffs, US companies are transferring manufacturing to China just to meet a quarterly number on Wall Street. (We should also do away with quarterly reporting. It encourages short term decision making to the detrimental of the US.)
