This is such an interesting insight that would never have occurred to me and seems to have a lot of explanatory power.
The global system of free trade and human rights has been the most free, prosperous, and peaceful era of humanity by far. Whole nations lifted from deep poverty, such as China and India (with still more to be done!). Incredible prosperity for the wealthy. Freedom, self-determination, democracy and human rights as the global norms.
Why are we throwing it away again? Much could be done to reform it, but we'll just throw it out?
Because we haven't figured out how to square allowing people the freedom to work in the industries they please, no matter where in the world that industry has found itself, with allowing countries to strictly limit who is allowed inside its borders.
The "just learn to code" message never sat well with those who have no interest in coding and now they are rising up to try and take back, so to speak, the work they actually want to do. The far reaching consequences that go along with that are not of their personal concern.
"Brain drain" is a always hot topic in my country. Many people from here move to the US for access to certain industries, tech included. They aren't going there to do whatever arbitrary work they can find.
Those in the US who love manufacturing aren't moving to China, but that's the issue: They, unless they have something really unique to offer, are going to find it difficult to. Hence why they want to see that work "brought home".
That's a good point; I wasn't thinking of that. Still, the number of immigrants to the US for 'brain drain' jobs I'd guess is relatively small, and Trump supports them to some degree - he likes wealthy immigrants, including in tech. Remember the recent (H-1B?) visa controversy.
> Those who love manufacturing
Is that really a passion for many people, working on an assembly line? I've read about it as a necessary job to pay the bills that almost nobody likes, and they want their kids to have someting better, etc.
