Even if we assume manufacturing does bring back high quality jobs: The people still have to leave their low quality jobs they are currently doing to fill those jobs. Which means the American people are going to have to give up something. Which probably means things like their Big Macs, with a return to home cooking like in the heyday of manufacturing.

A win from a health perspective, perhaps, but going back to the age where people didn't do anything other than spend all their free time maintaining their home life probably isn't what people are dreaming of.
