If you want an actual answer:
the ~30% of Americans who have a psychological need to see other people suffer, a media environment totally bought out by hard right billionaires, and an opposition that can barely distinguish themselves also propped up by hard right billionaires, and an electoral system that favors republicans
Without projecting some future non existing ideal, which of these hateful left wing authoritarian states would you refuse to visit, or live in? How much would e.g. the 5 year or more life expectancy they have over the US alter that or do you believe life there is so oppressed that even living longer would be punishment?
BTW this question does not mean I accept any or even part of your premise.
(I live in one of them and have lived in one other and visit all three, the US, the EU, China and other places frequently for work)
