Once you are labeled a deviant, you no longer care about keeping up with a certain standard. A person is likely to keep living a deviant life because of the stigma that is attached to him from the negative outcomes of his previous offences. One deviant act leads to another and then another and soon the whole social identity of the person has changed. They are labeled a deviant by society and cannot find work or respect so they continue their deviant behavior. Marxist view capitalism creates inequality.
People commit crimes because they are oppressed by the capitalist system.
They do not have the same access to societal privileges as others. In the US, the legal system reflects the ideologies and interests of the ruling capitalist class Law is the tool of the ruling class. People make laws to protect their own interests. The legal system perpetuates the interests of the ruling class. Capitalists commit crimes of domination price-fixing, dumping hazardous materials, unsafe working conditions they make the rules and break the rules.
