No. Every single one of them could pull $100,000,000 out of their personal money circulation and just store it in various stupidly safe places that barely return the rate of inflation. For all I know, maybe they all do that.

They have so much money that it’d be almost impossible to lose it all, but if they managed to do it somehow, then they could pull out that safe nest egg and still have more money than they could ever need in a lifetime. There’s almost zero chance that they’ll ever be poor.
