In the next 30 years: Is anyone predicting damaging "migration waves" in: Washington state, British Columbia, Argentina, Italy, Australia, South Africa, Japan?

In the next 30 years: Is anyone predicting damaging "migration waves" in: Washington state, British Columbia, Argentina, Italy, Australia, South Africa, Japan? That's just off the top of my head, I think the real list would be much longer than that. "The vast majority of island nations" -- this doesn't seem like much of a constraint in the first place? But are you talking about Japan, New Zealand, and Indonesia? Or Tuvalu and Fiji? "Not badly overpopulated" -- apart from a very small handful of countries, this doesn't shorten the list of locations. Do you expect latitude to matter in the next 30 years? My guess is that the ultra wealthy will, in general, not have "all their stuff" in one place. But also that most places are unlikely to take advantage of people bringing significant spending to the location. If the U.S. continues its current course, yeah, games and expansion are risk factors. But again, there's a long list of countries that meet this criterion. I'm just failing to see how we're headed for Mad Max-style anarchy in a human time frame.
