This is very well put together.As I grew up, my middle-class parents taught me not to pick fights with random people on the street, especially those lower in the social hierarchy. Their reasoning was clear. People with little to lose often show less regard for order. They develop a fearlessness and shamelessness born of hardship. It may look like bravery and can provoke you into a dirty confrontation, but in truth it is usually just frustration finding an outlet.
