I don't know if that's ever going to happen for a lot of these companies. Amazon for instance is a distributor and cloud provider. Apple more then likely won't ever fully bring manufacturing back, not with how little they spend in labor costs in Asia. Trumps plan to set a minimum salary for imported IT workers wasn't terrible, but i don't know if it had much of an effect.
For the most part a lot of manufacturing is going to move towards automation. Even the fast food industry is heading that way. in the next 10-15 years there are going to be a LOT of people displaced in the workforce by simple machines, we're(as a people) going to need to find jobs for them, otherwise they become dead weight on a system already being strained.
The really interesting thing about amazon is how little they actually make in terms of profits, while at the same time the owner continues to out pace the rest of the elite in terms of straight cash homie. It would be interesting to see what he does with his $156 billion dollars If i had maybe 2 of those billion and 5 years, I bet i could solve a good chunk of the homelessness.
