besides spend it on frivolous shit like yachts and planes and stuff, there's no way it's all liquid. do they just park all their billions in a bunch of investment vehicles and wait for it to propagate itself? don't they get bored of just waiting and watching line go up?
Epstein was a psycho monster even by the standards of your average rich sex guy. Most rich dudes just have one mistress at a time, they're not industrializing the rape of teenage girls. Fuck, they might not even have a real mistress, they might just be banging the receptionist who draws a salary from their company, or someone who actually has their own income and gets a boost from their sugar daddy.
Naw man, most rich guys have a few consistent women at once. It's honestly not that expensive, I looked it up once. Most "sugar daddy" arrangements average something like $3k a month which is fucking nothing to someone with a net worth of $50+ million.
