The Iron Law, and a corollary

In the course of discussion of the Muslim Student Union at University of California Irvine (articles here and here at PJ Media and LGF passim), Dr. Pournelle posts a corollary to the Iron Law.

Pournelle's Iron Law of Bureaucracy states that in any bureaucratic organization there will be two kinds of people: those who work to further the actual goals of the organization, and those who work for the organization itself. Examples in education would be teachers who work and sacrifice to teach children, vs. union representative who work to protect any teacher including the most incompetent. The Iron Law states that in all cases, the second type of person will always gain control of the organization, and will always write the rules under which the organization functions.

The corollary:

[T]hose who don't have another life take over organizations.

Context. And see below.

Update: and see Iron Law, another version, above.
