Go live a few months as an average middle class person in Western Europe and then do the same in the US. You can argue in favor of US superiority based on GDP and stock market and number of billionaires a hundred other similar metrics, but looking at basic happiness and quality of life there’s really no comparison. Europeans value maximizing family, community, physical and mental health, leisure time, hobbies, culture, and so their laws and policies are written in that way.

I think about this a lot as someone living in the north of England (in a nice town and quite well off) maybe ignorance is bliss but I just don't know how life could get much better, but then I guess some Japanese person living a prosperous life in a nice community might feel the same about where they live (and might not rate the type of life I lead) so I guess it's subjective..

As I said I think idly about this a lot because when you feel like you've found a sort of eudaimonia you want to share it. But whilst personally, I feel like I won life's lottery being in the place and time I am, but that doesn't mean it's the one true way.

Wherever people are, I hope it's the right place for them personally

Nah. I've spent enough time in Western Europe to know that's total BS. It's a nice place to visit but I wouldn't want to live there.
