High School Ball vs AAU Ball

I hear that most high school coaches argues, that most coaches in the AAU are poorly coached, because the players doesn't produce the right fundamentals of basketball and don't play defense, while in high school, the coaches teach you the basic skills, executing plays, and defense. The other problem, is when shoe companies like Nike, sponsors their own tournaments and offers money to coaches to sponsor an AAU team and to participate at their tournament. My question is does the AAU circuit needs to get structured, just like the high school system?
