The fraternity and intercollegiate athletic systems are the primary focus for university life in much of America. Mention a college and many Americans of a certain class will ask "What did he play?" or "Where did he pledge?" From their point of view, they are right to ask such questions since they point to the tribal bonding which will sustain the student throughout a privileged life, providing at its highest level access to vast unearned wealth, as on Wall Sreet, and at lower levels a membership in the right clubs and access to lesser business deals in places like Tulsa or little Rock. The fact that the fraternity boys, or team members, choose to mock non-members is natural since everything in their culture leads them to believe that they are better and more deserving than those excluded from their ranks. People are shocked when this necessary attitude manifests itself as a no longer fashionable anti-black racism, but would not be distressed if the boys were mocking dorks, dweebs, goths, hippies or some other vaguely defined out-group.
An economic system dependent on inequality will inevitably produce such obnoxious attitudes in young people selected for benefits that on some level they know that they have not earned and do not deserve.
