Iron Law of Oligarchies (...Institutions, Companies, etc.):

"...the people who control institutions care first and foremost about their power within the institution rather than the power of the institution itself. Thus, they would rather the institution "fail" while they remain in power within the institution than for the institution to "succeed" if that requires them to lose power within the institution."
