When Trump talks about bringing jobs back he really has to bring whole industries back. Over the last few decades we've pretty much gutted or out-right exterminated the domestic TV and consumer electronics industry, textiles, furniture, computer and cell phones, appliances, steel, etc., etc. For those jobs to come back you have to have someone willing to invest in rebuilding those industries pretty much from the ground up. Who will be willing to make that investment?
Capitalists will when opportunities reappear.
