One of the theories of my wife and I is that the different generations react to the way they were brought up. Kids that were raised in the 60s and 70s by baby boomer parents who (generally) didn't put as much effort and attention into their kids' activities produced a generation who really focused on getting their kids into organized sports and trying to see they reach their full potential. Is the recent drop in youth sports participation a reaction to that by young parents who resented the constant drive to practices all the time? Or is it a function of shrinking middle class disposable income?
