Your PCs are rich. What do?

From discussion about a Resources-heavy group in a World Of Darkness game, monsters should rarely have money problems, but Resources can be seen as a chance to solve every problem by throwing money at it.

Being able to hire NPCs to go on adventures for you seems like a cutoff point for a lot of adventures.

If you want to run a game about rich people, what kind of gameable things do they get up to? Courtly politicking is still an option - I could run Vampire about fancy elitist pastimes, sure. But something all like that, Succession style?
