Subcultural theories stem from Merton’s idea that the working class suffer from blocked opportunities to achieve success by legitimate means. For example, Cohen sees working class youths as culturally deprived as they have not been socialised into the mainstream, middle class culture. As a result, they lack the means to achieve in education and find themselves at the bottom of the official status hierarchy. Their failure gives rise to status frustration. The delinquent subculture that they form or join is a solution to the problem of status frustration: by inverting mainstream values such as respect for property, working class youths can gain status from their peers, for example, by vandalising property. Cohen’s theory thus helps to explain why the working class are more likely to commit non-utilitarian crime. Cloward and Ohlin build on Merton and Cohen and they use the concept of illegitimate opportunity structures to explain why a range of different crimes are more prevalent within the working class. They identify a criminal subculture in stable working class neighbourhoods that offers professional criminal career opportunities, a conflict subculture of gang violence and “turf wars'' in poor areas with a high population turnover and a retreatist “dropout” drug subculture made up of those who fail in both legitimate and illegitimate opportunity structures.
