you'd be surprised! people seem to have a limitless appetite for that money stuff. they just can't get enough of it, i've found
Most are happy and stop at multimillionaires, but of course we don't hear about them. The focus on hungry billionaires is survivor bias.
We don't hear about Tom from MySpace.
How much money do you have? or are you just commenting from the peanut gallery?
I know some pretty wealthy people. They are very aware of those who are 10x wealthier than them. If Noam has 1B, he is probably pretty aware of those that have 10B. He's met them and seen their properties, scope, and powers. Likewise, they are thinking about those that have 100B, and those are thinking about Elon, who now has "four commas."
