Sadly, the US, where I currently live, is quite behind in this. Considering going expat (not for this specific reason, but it doesn't help); any expats have recommendations of what countries have worked well for them?
Heavily depends on money available / crime level tolerance - albeit crime level in the US is pretty crazy.
Europe is deteriorating incredibly rapidly in terms of crime (due to a combination of economic poverty and uncontrolled immigration from third world countries) - but I think some of the low tax EU countries (Malta, Cyprus, Gibraltar, etc) are a good bet for a few more years.
My top choice if I had family (or friends I want to be close with) in the US would be Cayman.
I think long term, either South America drops the level of crime considerably and becomes the new place to be or China start building futuristic cities attracting wealthy western talent to offset their declining population rate.
I recommend you first narrow it down to somewhere whose main language you can speak. I picked Germany because I already had some experience with the language and slightly Dunning Kruger'd myself. I like it, but… well, even native German speakers say „Deutsche Sprache, schwere Sprache“ ("German is hard").
Cyprus has a lot of English speakers (and indeed a lot of street furniture that looks just like the UK, plus two UK airforce bases[0]), but the national language is Greek… I don't know if I'd risk that, given the one time I tried to ask for «Ένα σάντουιτς και ένα τσάι παρακαλώ»[1] in Athens[2], the person behind the counter replied in English to correct my pronunciation.
