There's no reason the US can't onshore its industry again... But the process (and the products) will be prohibitively expensive, such that without astronomical subsidies (which the US certainly is pumping out, money printed go brrr) the only viable markets for such goods will be captive markets.

Rebuilding the industrial infrastructure, etc. will be hilariously overpriced. Rebuilding the ecosystem (base of engineering, R&D, etc) will be hilariously overpriced. The labor costs will be hilarious overpriced (because the workers' living expenses will be depressingly overpriced- Yankkkeestan and the collective west is expensive as all hell). The valuations, final cost of production, etc etc... will all be hilariously overpriced. And each and every capitalist will... "capitalize" appropriately on the situation to whittle out their cut.

What I'm saying is- China will be building a bridge in a few months to a year, and often doing it under budget and generally with great quality. Africa, Asia, Latin America will build their bridges, and it will take (varying amounts of time), and it will cost considerably less than it would in the US or anywhere in the west for comparable quality. Same with Russia, etc.

The US will use its money printer to magic up the funds to build a bridge (or even just repair it lol) and will wind up going massively over budget, will probably not have completed it within a decades time, will cut corners here and there (and won't even maintain it properly... Because everything in their system is so overpriced), and will have what may as well be infinite grift and corruption (probably legalized in one form or another). All the "capitalization" adds up lol...
