The US had and has plenty, which is why manufacturing started in the US and migrated out once processes standardized enough to bring in less competent labor. Then labor became more competent, so more companies moved their operations there. A lot of US manufacturing engineers work with Chinese manufacturing facilities, because that’s where the labor is.

If the US wants to bring manufacturing back, it needs to be cheaper to do it domestically. That means automation, better materials transportation, and cheap raw materials.

I don’t see the point. Instead of bringing back manufacturing, improve education and focus on higher value work.
