This would be the subculture of which Red is the ringleader, a subculture that provides the other inmates with anything they need for a price. Akin to a black market, this subculture uses trade in order to provide inmates with things they desire, from smokes and magazines to drugs and alcohol. As Red maintains in his narration, "There must be a con like me in every prison in America. I'm the guy who can get it for you. Cigarettes, a bag of reefer a bottle of brandy , damn near anything within reason. Yes sir, I'm, a regular Sears and Roebuck" (Darabont, 1994).
In conclusion, it is readily apparent that within the overall prison culture there are a number of distinct subcultures that emerge in the years made up of what Red calls "routine," (Darabont, 1994). Most inmates who are part of a subculture will remain part of that subculture until they are released from prison or meet their deaths from some kind of violence inflicted upon them by another subculture.
