I live in Philadelphia. We had a lot of manufacturing here, but most of that vacated the city center in the 1970s and 1980s. I recently was doing some research into urban renewal around my neighborhood, and found a paper about the city's efforts to address a concentrated population of perpetually drunk homeless men, mostly centered in my neighborhood, mostly squatting in abandoned buildings or living in flophouses. The city's approach was effectively to remove them and spread them out - and bulldoze the neighborhood to make way for a federally funded highway, now I-95. A lot of manufacturing businesses just called it quits - the owners had made their money on the backs of cheap labor and hadn't really set up any kind of succession plan, but could retire comfortably. Others moved, mostly out of the city, and by the 90s, that labor was moving overseas.
And that's why I don't really foresee that kind of manufacturing coming back here. In order to survive the race-to-the-bottom pricing that the majority of Americans crave, you need a large labor force that will accept some form of sub-par living conditions. But if you can't earn a living wage, you can't afford to participate in the economy in a way that supports the manufacturing, and then you're back to those mid-century slums.
I'm dramatically oversimplifying things, my main point here is, I didn't really put together how much of early 20th century American manufacturing relied on chronically drunk homeless men.
