Marxism explains that society is unequal and is divided between the rich and poor. The poor are over-policed, the rich make up the rules and use punishment as a way of social control of the poor-working class. The rich get away with more crimes as they are not focused on. The poor don’t have an opportunity for education and good jobs - the rich keep the working class poor, this results in an unfair society. The poor need to commit crime to have money for themselves and their family as they don’t have legitimate means to make money.
