Like I don't know, massive amounts of solar panels and wind turbines? To reduce our dependence on foreign oil and energy?

No, I must be crazy, that could never work because...? Because? Because they wont let it happen.

USA is the 3rd (IIRC) most populous country, with a very high purchasing power parity. Even if they start manufacturing, they will not find as many buyers.

And how do you propose that happens?

Usually, instead of tariffs currency fluctuations form natural tariffs. However the Chinese artificially lower the Yuan.

I think an alternative could actually be tariffs. Just not the way Trump implemented them. Do them slow and steady. Announce you will up them 1% each month for certain goods. Promise you will keep them for the long term, so get broad political backing for them.

Just doing them on a whim is not something that gives people or companies confidence to invest into expensive factories, training and resources.
