women will like me if I work in a factory because it's hard physical labor
Just go to a gym if you want to work hard at something physical
because it pays well
Unless you live in a high COL area or get lucky with a specific company, probably not. Go into trades, it has everything people like this want and pays way better on average. There are plenty of openings for those already.
because we can make it cheaper
You can literally never compete with chinese child slave labor conditions in terms of cost efficiency, unless there's somehow a major technological breakthrough that somehow doesn't make it to China. There's more people and they pay them less. You can make an argument for quality but the niche of "mass produced cheap convenience products" that China dominates don't really have quality as a top priority anyway. Does a person *really* care if their shitty $5 Walmart T-shirt doesn't fit perfectly snug? I doubt it. The industries that require advanced manufacturing technologies to reliably complete with quality are mostly already here.
I genuinely don't know who this is supposed to appeal to. Yes there will be more jobs available assuming the plan even works, but there's already better options available. Sucks that people are getting exploited but it's either them or your own children until the world grows comfy with mass-produced goods being fully automated.
