I typed a long, wordy response that would have made an English teacher, like Coach Chass, proud. And, then, my computer crashed.
Suffice it to say, there is a beautiful ying/yang relationship between the high school and club systems. When you coach both, it is beautiful to see how each one nourishes the other. I agree, that for the few kids who can get into a professional club or the top 1% who could become national team players, high school may not be for them. But There is an almost perfect cycle between the two seasons that develops and encourages kids to play year-round.
