It is a crime committed by people from a lower social class, often just for personal gain, like a mugging or armed robbery. This differs from more sophisticated crimes such as embezzlement, which would be committed by people of a higher class on a larger scale and are referred to as white collar crime. Blue collar crime could be by an individual or a gang.

Both has aspects of them which can be considered worse than aspects of the other. Perhaps the biggest pitfall of white collar crime is that it's prosecuted and punished much less and much less vigorously than blue collar crime... you can embezzle millions, destroy the life savings of many people and take away what they've worked their whole lives for, and you'll receive a light sentence at a federal prison. Steal a couple hundred Dollars (if even that much) through more direct means, and you'll receive a significantly longer sentence in a state prison.
