Imagine being a poor, homeless person sleeping on the street in NYC. Then you hear a splat and see a dead body that just landed in the street. The body is an investment banker who committed suicide by jumping out of the 110th floor window. You ask why he killed himself, and someone tells you, "the stock market crashed, and he lost millions of dollars"
"So, he had no money left?" you ask.
"Oh no, he still had lots of money, maybe a couple million still" you're told, "it's just that this morning he had hundreds of millions, and this afternoon he only had two million."
From your perspective as a homeless beggar on the street, it's retarded that a rich man would kill himself because he's less rich ...though still richer than you are.
Foids get insecure for the same reason rich people jump out of windows when the stock market crashes.
