There’s no world in which large scale manufacturing is returning to the US. Not only are our labor costs dramatically higher than in east asia, but we also lack the logistics infrastructure to quickly produce components and get them to their next stage of assembly quickly. And we can’t just build that stuff because we don’t have a totalitarian government that can just bulldoze farms and houses to run a highway or railway. We also are less interested in pollution, which raises the sticker price on US manufacturing.

If we’re serious about it, we are going to have to commit ourselves to economy-tanking tariffs (like thousands of percents) for many decades until the US worker is as poor as the Vietnamese worker.
