For return to happen you need to have a creative economy, not an extractive economy.
Offshoring happened for the simple, dumb reason that it's cheaper and more profitable.
For all the rarara about "America", shareholder patriotism extends exactly as far as quarterly returns. If that means selling out ordinary US workers - do it. Give me the bag.
What offshoring revealed is that the US is not a culturally integrated country. The culture of the top 5% or so considers itself completely separate to the rest.
It's a political fault line that was always latent, was somewhat suppressed from the New Deal to Carter, and then came roaring back with Reagan.
Now it's operating at pathological, self-harming levels. The marrow of the country has been chewed out, and a few dysfunctional shell oligopolies, propped up by a bubble, are keeping the lie spinning.
There won't be any significant reshoring until there's a cultural change. Reshoring is just too expensive for the owner class to do more than tinker with it. Without a cultural change the owner class doesn't care enough to change that.
