Since the jobs are low paying, we should create a new class of worker visa and bring over folks from developing nations to work these jobs.
We should build the exact same factories they have in China, but staff them with immigrants from Latin America, Asia, and Africa. The wages wouldn't be great, but we could build the factories in LCOL areas and extend citizenship as an additional carrot.
Bringing the factories on shore would let us be prepared for the upside of eventually automating it all. I don't think we can do that unless the factories are already here -- you can't will fully automated factories into existence from nothing, with no demand and no know-how. We can manufacture that demand now if there's enough political will for it.
Immigration has always been our real superpower... We should double down and get people to immigrate and work in new factories we spin up within CONUS.
