"Bad- A radically increased emphasis on revenue. ....this organization is supposed to be about people, not cash."
Don't blame EAA for all of the cost increases. I learned a few years ago after volunteering at the Ducks Unlimited Outdoor Expo (from a DU director), that used be held on the EAA grounds, about a month after AirVenture, that a lot of the costs (like camping, exhibitor spaces, etc.) are set be the Oshkosh Convention Bureau... or board, or whatever they call it.
It's kind of a long story but, to make it short, I was going to send off a nasty letter to EAA for charging the relatively few DU volunteers overnight camping fees. ("DU leased the grounds. How much money does EAA need?" I thought.) When I talked to the DU director about my concerns he told me that EAA had nothing to do with that. It was all dictated by the OCB.
