In Common

There are similarities among republics, political parties, unions, etc. They are meant to be mutual benefit organizations. The are expected to have, as central to their being, a democratic process which provides for participation of, and control by their members. Another set of similarities they have in common is the ways in which they displease publics and lose memembers, I list much of that set below:
~ movement toward oligarchic control,
~ displacement of prime beneficiaries,
~ goal displacement,
~ means which are perceived as illegitimate.
~ low level of participation,
~ leaders retaining and extending their power,
~ military or police power tending to dominate,
~ original objectives lost sight of,
~ lack of understanding of goals of organization by its members or publics.

In which organization you know have you noted such tendencies?
