We need robot powered factories that require 1/10th or less the manpower of a normal factory. Then the extra cost of US wages matters less, and with the rising cost of shipping - it’s now both quicker and cheaper to build in the US.
We need a draft for technical trades. Not like they’re doing anything else.
Not really? Factory work is hard, but generally pays well and has consistent long term demand (aka job security). Machining is skilled labor and paid like it, and factories that work with metal are far cleaner than others. Ironically, the dirtiest and most hazardous factory I've seen/worked in was a laundry soap factory, hands down. Nobody making parts that require consistent quality can just not give a fuck like that or depend on a pipeline of disposable desperate temp workers for production.

Do you know how a modern factory works?
There are tons of crappy grunt jobs still in the factories America has left. Outside of a few industries, it's there isn't margin to do that.
And as others have pointed out, our factories are heavily automated but you still need humans.
Japan, Korea, Taiwan are allies and I don't see any reasonable future where that's threatened.
The main issue is that Taiwan is directly threatened by military action by China. Even if Taiwan remains friendly with us, a war in that region would cut off our supply of chips.
