In a more recent case, a homeless bum set an elderly man on fire for not giving the bum money.

Anyway, I guess what I'm getting at is the classic difference between book smarts and street smarts. Here's one example, people with money (PWM) will try to figure out how to kill a bear with their equipment. A person with street smarts will just run faster than their companions. In that example, I think the street smarts trump the book smarts for survival purposes.

I admit I have more book smarts than street smarts. I enjoy picking up street smarts here and there, but the mental link to the "street knowledge" is not as direct as other folks who basically live in the streets or live in the woods.
