I believe this is also what colours our views of the general academic infighting — academics are rarely rotated out except in the lower ranks, so it's a different type of skillset of building long-term alliances that drives their progression through the academic field and available careers in a particular institution (not even talking about "academic points" through publishing in recognized journals, which is a different discussion altogether — even with that criteria satisfied, to move to the next rank of professorship, you need to be elected by your colleagues).

Basically, academic tenure is opposite from democracy.
