Why should manufacturing jobs be well-paying? Human productivity has not kept up with business improvements at all. A contemporary robot can assemble car modules much faster than a robot from, say, the 60s. A human now works at the same speed as a human from the 60s.
"The US can't make anything" is an absurd delusion. We are the second most productive economy in the world.

We are fully capable of meeting our defense needs already. If you really care about reinforcing our military-industrial capability the best way to do it is to arm Ukraine.
