I would say that the upper class of each country has a distinct subculture. And now those subcultures have somehow converged into a global subculture of the rich.

A golf club membership for example can cost $100,000. Some people will probably never save up that much, and if they did, they would never spend it in a golf club membership. But for some it's completely normal and part of their everyday lives.

Same with schools, same with restaurants, etc... by being strictly exclusive you set yourself apart from the rest and miss out on a lot of things.
