I think living anywhere other than your home country for a while is a valuable experience. You learn to not only recognise the flaws in your own country (which you can then push to improve), but you also learn to appreciate what you previously took for granted.
That is what it was for me when I moved to the US from Switzerland.
Only then I realized that the way people live in Switzerland is not something you can take for granted and in the end made me move back.
I always hear people complain about the Swiss mindset and how they should be more like silicon valley. But what these people don't realize is the reason Switzerland is the way it is is because of the mindset.
That's one of the most pernicious things about the US tax system though. Because citizens get taxed by both the USA and the country they're in, it strongly disincentivises people from ever moving abroad (unless they revoke their US citizenship).
This leads to Americans never really discovering, en masse, what life in foreign countries can be like. They're just tourist destinations.
This and unless your country of residence has lower tax rates than the US you merely end up filing, not paying the US. If the tax rate is lower, then the tax hit is what you'd pay in the US less the foreign tax credit. Only thing would be tax free income in your country of residence that is taxable in the US...
I moved out the US just for a few years. Almost a decade later I still haven't returned. And when I seriously contemplate picking my return date I see events in the news like Michael Brown, Tamir Rice, Sam Dubose and think why should I move back.
Wow you cherry-picked 3 examples (see confirmation bias) and thought stuff like that happens to every single person in America pulled over by a cop (in a nation of 300M+)?
It happens all the time in the Bay Area. Pretty much every week I have friends who are either witnesses or were very close to shootings or situations with police brutality. Hell I stayed there just for a few months and I saw firsthand a cop restraining a person with a boot up their face. I had never before seen anything like that, and I've been to some pretty violent places.
