That's pretty lame. There aren't more shoe makers and t-shirt makers in the US. And I don't want to import Mexican laborers so that we can open more of that kind of business here. I'm perfectly fine with Mexico and China making shoes and t-shirts. We'll make the construction equipment, farm equipment, airplanes, and other stuff that they can't make.
China will be making heavy equipment inside of five years. They'll be making airplanes in ten.
As for shoe and t-shirt manufacturers, I would lump small manufacturers of all kinds in with them, such as small tool and die shops, etc. Many of those have already gone to China.
None of those jobs are coming back. Ever.
