I assume you didn't start the thread just to get unanimous agreement. I'm not sure it is any worse or better than any other industry. I'll use some generalities.
First, barriers of entry. Bachelor's degree in a lot of places, have we hit 40% of the population having a BS/BA yet?
From there, you can whittle down the type of people who can't find their own a-hole, no talent, who don't want to work that hard, etc. Again, there is a reason you have 55 year olds who aren't executives, and it isn't because they used to be one.
You further this by people who even want to be in coaching. Family members in coaching makes sense, people like to do what is familiar and what they know, usually through their parents, and this happens with lawyers, doctors, engineers, and waiters.
I think it isn't all too dissimilar from any other field and so I'm not terribly surprised. Go look at airline executives or any other industry. They just go around the competitors as VPs until they retire.
I'll even throw in mediocrity in other fields isn't punished either. Basically, for the most part, if the wheels don't completely fall off or you avoid embezzling, you'll always find another executive gig once you've had the title once. This is why people change jobs for "titles."
