There was a thread here not too long ago about employees getting fired because they were cheating on their expense accounts. C-level execs cheating on pretty trivial amounts. And others brought up star athletes getting paid millions, then getting busted placing thousands of dollars on insider bets. There's a lot of irrationality in these decisions.
Greed knows no limits. That's how polls showed the happiest people earn around 60-80k a year, and both the people below and above that threshold, reported to be less and less happy the less they made and also the more they made.
It's as if the more money you make, the more you need to feel fulfilled, so people start stealing and scamming to cover a self inflicted psychological money deficit.
