Why I'm a Libertarian:
Pournelle's Iron Law of Bureaucracy states that in any bureaucratic organization there will be two kinds of people":
First, there will be those who are devoted to the originally intended goals of the organization.
Second, there will be those devoted to the organization itself.
The Iron Law states that in every case the second group will gain and keep control of the organization.
That's the group that will set the tone, write the rules, and control promotions within the organization.
*(I would add that the inevitable result is that those the organization was intended to serve, are inevitably the ones that suffer.)
