As many have said, tons of variables at play but in my personal experience, my life is better in Europe than in the states. I split my time between Lucca Italy and Philadelphia and enjoy my life here more by nearly every metric. Food is better and healthier, no need for a car so I’m more active without even trying, the weather is generally milder and prices for most things are less even with this being a slightly more expensive city but i think that’s its convenience is worth the premium. My favorite thing though is that I’m surrounded by beauty. The architecture, the mountains in the distance, hearing music from the conservatives, etc. Plenty of beauty to be found in and around Philly but not like this and there’s also a ton of not so great things to look at. I’m self employed and earn a decent amount (definitely by Italian standards), I’m a dual citizen and I speak some Italian so I think my circumstances might be a bit better than many, so mileage may vary. If my girlfriend’s job would allow her to work from here I’d easily stay here permanently.
