I'm surprised you find the race unnecessary, but continue to include the gender. "Rich people" would be all that's required.

Isn’t a random sample out of the set of rich people going to yield a lot of whiteness and dudeness though?

I’m surprised you find the gender unnecessary, but continue to include the species. “Rich individuals” would be all that’s required.

The term "dudes" is not specific (colloquially, anyway) like "white".

The problem with "rich people" as a phrase is that most rich people don't think of themselves as rich - for example, only 13% of millionaires do [1]. As "white dudes" are disproportionately represented within this demographic, I think the inclusion of these qualifiers helps to illustrate the point.
