I've heard a conspiracy theory that it is a way to ensure reproduction of social class. Students of lower class have fun in the environment where jocks are most revered, and grow to have little economic power (barring the few who become sports stars). Students of upper class are educated in highly competitive private schools or top public schools, where the culture is similar to Asian ones, reproducing their upper class status when entering society.
