I worked with homeless people for ten years and people don't understand just how reluctant people are to move away from where they know. When you have nearly nothing , the few things you do have are much more Important to you. That includes your social connections
That's interesting, but there are different personality types, maybe some could benefit more from a fresh start?
We are not all so tribal. I emigrated at a moment when I felt I had nothing (except a web-model), this was a a good move, at least for the first few years.
