That sounds like upper middle class, where they still work for their money, like lawyers and surgeons and dentists. At that wealth level it's still stupid to buy or lease a brand new car, and they still mix in with locals and go grocery shopping.

Not that they aren't doing much better than most, but that's not what rich means. If you're working a "day job" like lawyer/dentist, you're probably not rich.

The real rich fucks, you wouldn't see them on the street because they stop doing shit like that. They are the true owner class. They make money because they literally own shit and rent it out. Gated neighborhoods at minimum, pay other people to buy groceries for them and cook for them, pay other people to do all sorts of shit so they don't mingle with the lower classes, and sometimes just working from other countries and moving around because they can.
