This is kind of off-topic, but I couldn't help replying. I'm not a famous author, so this never gained public traction, but I beat Jerry by about a decade and a half.
BITD, circa 1996, I was working at DEA and a DEA buddy of mine was temporarily living at a monastery. I visited him and ended up in a conversation with the Abbot. I was bitching about the admin/bureaucratic side of DEA and he says "that sounds a lot like the Catholic church." We eventually came up with a theory about all organizations that is very similar to Pournelle's Law.
Grunt members of an organization are either good at the mission or they aren't. Grunt members of the organization either believe in the mission or they don't. If they are good at the mission and believe in it, then 99% of them stay at the grunt level and continue to do the work of the organization efficiently and effectively. Management is a different game, so the members who suck at the actual mission promote to get into a different job, that they may or may not be good at. Members who don't believe in the mission promote because they just want to be a boss of something and they don't care what. Consequently, almost the entirety of any organization's leadership will be composed of people who either suck at the mission or don't believe in it.
Maybe my retirement career ought to be writing books...
