> children from generational wealth who play obscure sports from an early age to give them an edge in admissions

This sounds like a cut scene from Wes Anderson's 1998 film Rushmore. Can you name some of the sports? This sounds like fun. In my mind, the #1 prestige sport is rowing. It makes golf look like a sport for poor people. Also: Dressage (show jumping with horses). To be clear: I still respect people who are very good at rowing or dressage, but they are almost always from uber wealthy families.
