I once read somewhere that the issue is that to the old rich money isn't a topic. It's something that exists and has existed for a long time, that gets used when needed, but doesn't get talked about.

New rich on the other hand feel the need to display the fact that "they've made it", talking about money is important to them.

So there's a certain incompatibility between old and new rich, where old rich feel bothered by the talk about money.

I think in general money isn't a topic amongst the rich. Yes, there are exceptions, but in general it's a very boring thing to talk about once you reach a certain level.

Showing off is another way of talking. The need to show off is to compensate for something.
