I suspect as a group grows, formation of some kind of hierarchy is basically inevitable. Jockeying for status is a very deep human behavior. I expect groups that explicitly disclaim hierarchy to have a de facto hierarchy of some sort or another.
Contrary to what we would like to believe, there is no such thing as a structureless group. Any group of people of whatever nature that comes together for any length of time for any purpose will inevitably structure itself in some fashion [...]
For everyone to have the opportunity to be involved in a given group and to participate in its activities the structure must be explicit, not implicit. The rules of decision-making must be open and available to everyone, and this can happen only if they are formalized. This is not to say that formalization of a structure of a group will destroy the informal structure. It usually doesn’t. But it does hinder the informal structure from having predominant control and make available some means of attacking it if the people involved are not at least responsible to the needs of the group at large. “Structurelessness” is organizationally impossible. We cannot decide whether to have a structured or structureless group, only whether or not to have a formally structured one. [...]
Elites are nothing more, and nothing less, than groups of friends who also happen to participate in the same political activities. They would probably maintain their friendship whether or not they were involved in political activities; they would probably be involved in political activities whether or not they maintained their friendships. It is the coincidence of these two phenomena which creates elites in any group and makes them so difficult to break.
These friendship groups function as networks of communication outside any regular channels for such communication that may have been set up by a group. If no channels are set up, they function as the only networks of communication. Because people are friends, because they usually share the same values and orientations, because they talk to each other socially and consult with each other when common decisions have to be made, the people involved in these networks have more power in the group than those who don’t. And it is a rare group that does not establish some informal networks of communication through the friends that are made in it. [...]
Once the informal patterns are formed they act to maintain themselves, and one of the most successful tactics of maintenance is to continuously recruit new people who “fit in.” One joins such an elite much the same way one pledges a sorority. If perceived as a potential addition, one is “rushed” by the members of the informal structure and eventually either dropped or initiated. If the sorority is not politically aware enough to actively engage in this process itself it can be started by the outsider pretty much the same way one joins any private club. Find a sponsor, i.e., pick some member of the elite who appears to be well respected within it, and actively cultivate that person’s friendship. Eventually, she will most likely bring you into the inner circle.
All of these procedures take time. So if one works full time or has a similar major commitment, it is usually impossible to join simply because there are not enough hours left to go to all the meetings and cultivate the personal relationship necessary to have a voice in the decision-making. That is why formal structures of decision making are a boon to the overworked person. Having an established process for decision-making ensures that everyone can participate in it to some extent.”
