Richard-
I don’t think the answer is in bringing back the hard, labor-intensive jobs. Those clearly are gone for good, and that is a good thing. You wouldn’t find many people in the US willing to stand in a hot, dusty wood factory manually cutting parts for 12 hours at a time at any wage, let alone at the wage the Chinese or Vietnamese get. But the cost of labor (and materials, and shipping) has gone way up in those countries in even just the last 5 years. It’s not apparent to most people, because we’ve compensated by stripping down the product to hit the same retail price. It might be different in apparel or electronics, but that has definitely been the case in furniture.
Realistically, where is the next cheap labor source? Myanmar? Sub-Saharan Africa? There are plenty of people in the world who might be willing to work cheap, but they tend to live in countries with no natural resources, no infrastructure, rampant corruption, and unstable governments.
What you’re going to see instead, I think, is crappy manual labor being done by machines. This has been the arc of progress for decades, if not centuries. I see the mass manufacturing migration to Asia as a temporary detour. Once you have a fully automated furniture factory sitting in Vietnam, you have to ask yourself why you put it there, thousands of miles away from its source of raw materials and customers. You may as well just put it in the US.
And the jobs necessary to support that factory (engineering, maintenance, QC, packing, design, sales, support) require a wide range of education levels, and for the most part aren’t the sort of back-breaking drudgery that first-worlders increasingly refuse to do.
Ultimately mo-i is right, to have an actual economy, someone has to make stuff, grow stuff, or dig stuff out of the ground at some point.
