I think American attitudes are prevailing in a lot of things, hence comments about cultural imperialism. Not surprising really, nor Americans not really noticing it - it's hard to notice the idiosyncrasies of the place that inculcated you. It takes an American or other outsider to notice the strange habits or ideas that shaped me in Britain, and vice versa.

Just by seeing those mostly US views everywhere online my kids and their friends have a more American view, whether that's in social mores or simply not being aware that EU or UK have better consumer protections or other differences. It's rather sad to see everywhere slowly homogenising.
