I wonder if this is actually true. I see very few Americans taking every possible opportunity to make bombastic statements about how their lives are better than everyone else's (at least on HN). This conversation seems quite asymmetric from my perspective.
> Maybe you're just bitter?
This comes off as psychological projection.
Very few Americans have any experience about how life is in Europe, while the contrary is much more common.
I'll just say that I don't think the reason is a lack of knowledge and leave it here.
Your observation: Online, Europeans assert they have a better quality of life than Americans, while Americans do not assert the reverse
Your conclusion: "idk maybe they're lying???"
But to respond to your point, most everywhere is great if you're rich enough. Saudi Arabia is pretty rad if you happen to be in House of Saud.
