Your argument doesn't even make sense. Graduate from high school, take a business course, and perhaps I'll take you seriously. Freakonomics is a nonfiction book written by an economics professor at Chicago U. What are your credentials exactly?
Stats from a gang in Chicago.
The boss makes $66 hourly, or ~$100,000 a year.
His three officers make $700 a month, or ~$8400 a year.
Foot soldiers make $3.30 an hour. $530 a month full time, ~$6300 a year.
(Freakonomics p100)
$6360 =/= $100,000.
Why would a foot soldier would want to work for $3.30? Simple reason- The opportunity to move up in the organization and make more money. Moving up is unlikely to happen due to the large numbers of other workers. Your chances of getting a promotion are slim when there are 100 other individuals exactly like you. Gangs function almost exactly like corporations, except that they are dealing in slightly more illegal terms.
^Guy above me has it on lock though. Congrats for actually being intelligent.
