Romanian programmer here (I still live in Romania), I would choose another European country over a well-better paid job in the US in almost all cases, the reason being that that way I'd be closer to home, we actually have decent healthcare in Europe and the social contract as a whole is more robust compared to the US (it mentally helps going out on the street and not seeing the multitude of homeless people that I've read one can find on the streets of San Francisco), public transport is decent to exceptional and for me personally there's also the gun-control issue (or lack of it, more exactly), I really don't see myself living long-term in a country as gun-loving as the US is.
