People have a poor perspective on what, exactly, constitutes "a lot of money."
What I mean by this is that for most of us, after a certain dollar amount money becomes essentially fictional. In my brain there is no functional difference between a few million dollars and five hundred billion dollars, because I'm never going to have either amount and wouldn't know what to do with it even if I had it (with that said, if anyone out there would like to give me five hundred billion dollars, I would love to try and figure this thing out).
