I lived in the UK for two years (as a European), and I couldn't leave fast enough. Adjectives that I would use to describe British culture: miserable, passive-aggressive to the point of dishonesty, complaining, petty, distrustful of everyone to the point of paranoia.
There are obviously many great British people and not everyone is like that, but the overall way people treat each other? Yeah nah, not for me.
I'm not saying US doesn't have its problems, but they're of a very different nature.
