Freakonomics guy talking about the economics of crack dealing.

"How do you feel about being poor and black in America?

A) Very good.
B) Good.
C) Bad.
D) Very bad.

or as it turned out:

E: Fuck you!"

Thats verbatim. This is a funny talk, at times, but the subject matter is very serious, and very interesting.

For instance, the average crack dealer made $3.50 an hour, and stood a 7% annually of being murdered.
