As far as I can tell there are at least 4 ways of getting rich. Either you luck into with lottery/inheritance, you’re born in it, you’re ripping of other’s labour, or you’re paid by a large community to do important work.
The ones that inherit it or leverage cheap labour to get ahead are the ones that are usually the ones we see.
Money itself doesn’t corrupt, it is the power it buys that corrupts. Money is one of the currencies. Owning a secret stash of tapes of very powerful men cheating on their wives with children is another currency with a much higher exchange rate.
