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?
I don't think there's anything that could happen that would change their lifestyle (well, maybe one thing), but they're still insecure because deep down they know they don't deserve it
I know rich people. I would say a lot of them do genuinely feel they deserve it because they've "worked so hard for it". But what they don't realize is that there's tons of poor families out there busting there ass much harder who aren't rich.
The is the other segment who are just rich because daddy was rich, and they try everything they can to justify that they deserve it, including just outright lying about doing work they've never done.
