I'm in the same boat. Have lived and worked in both and definitely don't see this drastic difference that's always espoused on here between the US and EU QoL. They're both pretty good places to live, with some differences in how you manage things (less taxes in the US, more things you have to buy for yourself).

You're obviously going to do better in a nation/state with more social services if you're in a very low-income manual labor/blue-collar field. People here pretend that that's 100% of the American/European populations in their weird ego-flexing comparisons.

Either way, it's not worth arguing the point with people on the internet. If Europe is so great, go live there. And vice versa.
