Carl hit the nail on the head. It's all about who can bring the most bucks to the table. Our chapter nominated someone as a candidate for the board once. He was well qualified, but when he attended a meeting of candidates, the EAA muckety mucks made it clear that he would not be on the board because he couldn't bring enough $$ to the table. Just follow the money. I really don't have a commentary on whether this is right or wrong, but it is the reality of the EAA Board. Like politics, follow the money, and you'll usually find the answer.
As for diversity, just select the most qualified. But that's not really what the EAA does either.
