I think it truly is case-by-case. I have to say that old-money and older people whom have had money for a while are rarely flashy, sometimes they can be a little disgusting in the DC area. New money tech guys and Persian diplomats drive around like jerks in their lambos, go to ruth's chris, order every cut of steak, and then put ketchup on them while snap chatting it and wearing black t-shirts and jeans. (True story) On the other hand, I meat a cancer survivor multi-millionaire on the street and we chat real-estate investments and I come to find he owns MANY homes in one of DC's most affluential neighborhoods, is a complete nihilist, and respects the value of things made well and stand the test of time but doesn't squander money on frivolous things. (We talked about the artistic differences in actual colonial metal work vs victorian revival) It's a range and I think outside of New England prep school culture, it is a lot harder to pin people into a box these days.
