to think that class isn't just a British thing

[WyclefJohn]

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?

but I still think someone from Mississippi would recognise an upper class Bostonian, and vice versa.

But that would depend on how well-travelled and/or well-educated the person in Mississippi is. I think many Southerners would just think "oh, here's another Yankee." They would probably just assume the person was middle class, possibly upper middle class.

Pretty much it.

birds I didn't mean that it wasn't good for us Brits to worry about the class divide, just concurring with the OP that class is very much present in other countries at least as much as it is in the UK.
