The two multimillionaires I know (one sold his company to JPMC, the other, to Google) aren't driven primarily by money. They have a genuine interest in what they do (securitizing carbon offsets, and designing analog circuits, respectively).

They're what you'd call "good guys".

They wouldn't be caught dead in that crazy kickback scheme that was described.

I know this is a small sample set, but what I've come away with is that rich people are like you and me, except they happen to be rich.
