Some hold that the large drop in price of cocaine made it hard for low-level gang members to afford gunsFrom How the Plummeting Price of Cocaine Fueled the Nationwide Drop in Violent Crime
All of this competition would most affect the foot soldiers in the cocaine trade, between whom the majority of inner-city violence occurred. Thanks to the work of Sudhir Venkatesh on the underground markets of the Chicago's urban poor, we know that drug gangs are highly organized and stratified. Those at the bottom selling on street corners make very little. Most only sell drugs part-time as a means of supplementing income. Few sellers pull in substantial earnings. In a study of Washington, D.C. dealers, Venkatesh found "25 percent of the sample sold drugs no more than once a week, and these people reported monthly net earnings from the drug trade of just $50 a month." The basic conclusion is that the lack of financial opportunities in the ghetto and the promise of climbing the gang's organizational ladder kept small-time dealers accepting low wages.And there's the missing piece in the DEA's theory. Once the margin of profit for dealing small amounts of crack cocaine disappeared, being part of the drug trade was no longer worth the persistent threat of violence or the stiff criminal penalties. A 70 percent drop in cocaine prices like the one that occurred in the mid 1990s combined with competition from decentralized sources for methamphetamines and prescription narcotics would completely eliminate the minimum wage drug dealer as a viable profession.
