Freakonomics author Steven Levitt presents new data on the finances of drug dealing. Contrary to popular myth, he says, being a street-corner crack dealer isnt lucrative: It pays below minimum wage. And your boss can kill you. Freakenomics is meant to examine the 'hidden side of everything' which to me sounds familiar to the concept of sociometry - the measuring of relationships. However, Levitt is an economist and was thinking simply about unconsdiered elements in any system.
