Darn! I wish I had time to read through your whole post and reply at length right now. I'm on my way out of DF til at least this evening.
But amen. That's why I said I think your model applies as much, if not more, at the social level. I should have added studio- internal comps.
IMO, if you're already at a public-access comp, you already have a huge source of information about how things work, how much they cost, how much everybody else is paying, what resources are available, what other teachers and their students look like, whether your own performance is comparatively good or bad. You have a HUGE amount of information that's there for the asking/observing/networking.
If you're in a self-contained studio, you may or may not ever get any of that information. So it's the luck of the draw. If you're affiliated with a reputable, good-quality studio, you're in luck. If not, you may very well get bilked and never know it.
Yep. You're definitely on point about the value of consumer information. I just think the people who really need the information the most, though, are not necessarily the ones you meet at NDCA comps (or even unaffiliated pro-am comps.) Those folks already have information, or at least access to it, IMO.
