According to the information in the video, coming from a middle-class (white) family significantly changes the outcome of a young person's primary deviance. The likelihood of a young person committing a crime is significantly reduced by being surrounded by a community of: conventional workers, adolescents and children in good schools, etc. The video also shows that the probability of a young person committing a crime is significantly reduced by being surrounded by a community of: conventional workers, adolescents and children in good schools.
This is very different from the situation experienced by a (black) young person living in a poor neighbourhood, surrounded by violence, where gangs are rampant on every street corner and the police force is relentless.
