It really amazes me that Americans move away from anywhere that has usable fresh water supplies and towards any place that doesn’t. Like we’re the wicked witch of the west or something.

The root cause is that once Americans move somewhere, a very large portion of them immediately turn around and try to prevent others from moving there, too. So you end up pushing people out to barren places.

		I don't believe it. People are leaving Detroit, not because anybody is trying to prevent them from coming. For that matter, Upstate NY is not particularly NIMBY but it does rain. On the other hand, people still want to seem to go to California but it's only a realistic plan if you're comfortable being unhoused. One of my theories is that people in Arizona hate the government and New Yorkers don't because in New York you can drill a well and take care of yourself but in Arizona you have to plug into a tightly regulated network and live where they tell you you can live and how they tell you to live.
