Robert you're in over your head on this one. it is not available to everyone. A good friend of mine coaches club volleyball in Texas. VB clubs generally start with 11 and 12 year olds. To play in her club you're looking at $6,000. That is not available to everyone. As for other options, sure you can go to Athens City Rec and play bump ball.
As for AAU, it's become a money machine for quite a few people.
If I'm in over my head, you'll have to give me another example as to how. I will admit, however, I know nothing about volleyball clubs or what they cost. I strongly suspect you can play club volleyball for far less than $6k. I KNOW you can play club basketball and soccer for far less than that.
You're throwing the highest figure you can find at me to prove your point, when you and I both know your example is not typical. And, your ignoring my point about "scholarships," which I believe most clubs offer.
Bottom line is this: Is it expensive to play club sports? Yes. On that we both agree.
Is it exclusionary? No more so than the cost of a Mercedes Benz is exclusionary. I'm not sure what you want here?For it to be free? For society at large to pay for it and permit no entrance requirements?
I feel like I'm arguing with idealism.
