Continental Europeans are known even by Brits to be uppity. In my experience too Europeans tend to have a superiority complex. Almost every single one I've dealt with (in the US, in Europe, and online) has had a creeping superiority complex. You only see it if you're not in their in-group, which is why the Brits see it of continentals.

Y'all have smaller more expensive houses and less luxuries than Americans. It's a fact that Americans enjoy a higher material living standard than Europeans.

I've been to Europe, and driving is more of an inconvenience than public transport. Also I nearly missed a train between two major cities in the same country and would've had to wait hours for the next one. I prefer getting around easily on my own schedule, going near or far, and having to pay less for the privilege.

Getting arrested or getting fines aren't a nice thing wherever you go.

Many places in Europe struggle with free speech by American standards, with the police even harassing people for online comments with unpopular opinions in some countries.

I live in the Western US. When I lived on the East Coast for a couple years I hated how you could never get away from civilization. Every couple miles was another town. Europe is the same way. Just look at a population density map of the western US versus Europe. Europe is worse than the eastern US, and the eastern US is too much for my liking.
