"Drug distribution is handled much like any franchised business. A central gang acts as the wholesaler. Individual gangs are the distributors. They pay a flat franchise fee to the central gang for the right to sell drugs in a particular territory." "A drug gang makes about 80 percent gross profit (calculated as the revenues minus the cost of the drugs sold). However, they then have operating expenses such as the wages paid to officers and pushers, weapons, the franchise fee (called a tribute), mercenary fighters, and funeral expenses. These expenses can reduce the net profit to small levels, although other gang activities such as extortion can offset this. If there is a gang war, fewer drugs are sold, and wage costs fall, but the cost of weapons, mercenaries, and funerals rise; overall, costs may decrease slightly, while revenues may decline significantly, leading to losses." "Thus there is surprisingly little money to be made in drug distribution at the franchise level. Pushers receive barely what they would make flipping burgers. The people who do well are high up in the organization at the central gang level." (Scott Woolley. 1998. "Greedy Bosses," Forbes Magazine, August 24.) a.
