Class gets discussed a lot on MN, and I often see someone say something along the lines of that is such a British obsession, and you don't see it elsewhere.
In my experience, social class exists in every country, because it's a natural result of what happens when some people have more privilege then others. In my experience, I've yet to visit a country where social class doesn't to some extent determine your success in life - be it from the US, to continental Europe, Africa, Asia and so on.
When British people go abroad, they may not recognise the cues, but I am yet to see a country where they don't exist.
AIBU?
