I've only managed to fly outside these states once in my life, and I want to do it again and for the rest of it. The culture I was born into was and is rotting from a group of humans that are too internally frightened and humiliated by their lack of knowledge and feeling like they are owed things. I don't want to live here, and I have been trying to find a place that would accept my mentality as a citizen of a small blue planet even though I come from here... but I always worry I am guilty by association :(
Live the rest of your life abroad if you’d like, but don’t do so believing that everyone in the USA is from the same culture.
I could be convinced of your position if you can name the common elements that justify the umbrella. It becomes even stronger if those common elements are the rotten ones.
Anecdotally: I married someone from a very different (USA) culture than my own, and their family feels as different from my own as some people that I’ve met from other countries, so that’s partly why I answer that question the way that I do.
I would say our business and media cultures are most homogeneous. No matter where you are in the US, a business conference feels the same. A meeting with clients feels the same. The same toxic personalities rise to the top. I’ve never been surprised by a director or CEO.
No matter where you are in the US, you turn on the TV, and even if it’s local news, you get the same predictable messaging. We’re all obsessed with appearance and status, even within our subcultures and across the political spectrum. Superficiality.
Infrastructure is much better than over here, which still looks like Shanghai in the 1980s.
Food though is questionable, there isn't any real "bread" section besides those cut up in loaves. We're not even European, nor do we eat that much bread (in the Andes region) compared to rice, potatoes, or even quinoa, but even we have fresh bread aisles too.
Burgers are nice, even if the cheese or rootbeer tastes off.
The stereotype that it's easier to talk to people, or find an SO elsewhere is very true, going back to how Americans rarely feel "open".
