Sammy moved to the city to seek work after losing his job as a welder. He found work that didn't even pay the minimum wage, but was made redundant when the firm went bankrupt. Soon after, his landlord put up the rent and Sammy was evicted when he couldn't pay. He began living on the street, using begging and petty theft to stay alive. He was shunned by respectable society and harassed by the police. His only companions now were other outcasts, some of whom were substance abusers; soon Sammy had a drug habit himself.

Question Analyse how Sammy's case could be explained by any two sociological theories of criminality.
