This ties in a bit with a recent thread on what obligation one has to improve the bad situation in the country they live in, versus just trying to move out and leave the mess to the less mobile.
ISTM it’s pretty clear that a LOT of people would rather live under political regimes or in societies different than the one they do. And it’s also clear to me that change in any society is largely controlled by the speed of the most change-resistant members of that society. Whether that’s vested interests = the current winners, or more about the preferences of the lumpenproletariat.
Which leads me to conclude that one of the most fundamental human rights is to not only emigrate, but to be allowed to immigrate to the situation of your choice.
We improve total human existence by letting people vote with their feet and letting the bad places become depopulated over time.
