That honestly sounds like a lot of spurious causal assumptions. The Rust Belt and coal mining regions didn't get economically depressed because people left. People left because of the economic collapse. You seem to be saying if all those college kids just moved back to Upstate New York, Pennsylvania, and Ohio, the people there wouldn't be mad about their economies being destroyed? Because they still would have been destroyed.

More people (economists/policy makers) just ignore the rust belt's (or local regional) problems, because aggregate GDP is going up and to the right and people just go where the labor is needed so everything is going great. We don't need factory workers anymore, just learn to code and travel across the country for a job what's the problem?

No, it's we don't need factory workers and factory towns any more, so travel across the country for a job because there's no alternative, the town is gone and nobody can save it. Learn to code isn't going to work for most people, sure, but travel across the country isn't something that can be avoided.

Not everyone is agreeable to this prescription because they live in X and can't or don't want to move, and they then equate economic growth / globalization with economic death, cause that's what it means for their town and that's my original point.
