I’ve lived in both EU and US, and EU definitely has the better quality of life for the average person. I 100% agree.
However if you are at all an ambitious youngster with huge dreams, the EU is where dreams go to die lol. EU living is what i’d call “coasting in life”. It’s a safe, sheltered life, the government is very functional and “takes care” of you which i’m sure is comforting for many. It’s not for everyone though.
In other words, I would recommend the typical person moves to the EU if they have the opportunity. Their quality of life would improve and they would be happier. For anyone that’s very ambitious or very talented at something, your efforts will pay off 10x in the US, and you’ll have a better quality of life than your EU counterparts.
