US manufacturing isn't coming back because they didn't stop it from leaving.

All the people who want "manufacturing to come back to the US" did not boycott companies leaving the US between 1980 and 2010.

I grew up in a city where we had 6 major factories. One of which was Maytag appliances.

Not a single person I know stopped buying Maytag appliances when they announced they were moving the plant to Mexico around 2006. Not...a...single....person.

Not to mention that the cost to move back to the US and build a new factory and hire American workers at roughly 3-5x what they pay Chinese workers, the cost of the end product would probably be the same as it would be with the current tariffs.
