What's the purpose of a bureaucracy? I mean, let's say we created a new federal agency, the Federal Bureau of Helping Little Old Ladies Cross Streets; what is its primary function?
Why, to help little old ladies cross streets, right?
Wrong. It is to ensure salaries and jobs for Federal Street Crossing Agents and their Supervisors, and pensions for their future retirees, in perpetuity.
Now, you may become a Federal Street Crossing Agent for the noblest of reasons. Grandma got run over at 5th & Elm when you were little, and so you busted ass in college so you could qualify for the elite bureau and see that nothing like it ever again happened to anybody else's grandma. Of course, once you start working at the Bureau, you spend all day immersed in a Street-Crossing-centric world, talking about the dangers of little old ladies and streets with other Agents, watching training videos, reading briefings... Why, if every American knew the real dangers waiting for their own grandma at the corner of 5th & Elm, there'd be outrage!
Meanwhile, the bureaucracy of the FBHLOLCS, realizing the only way to justify its existence and thereby secure continued funding, lobbies congress and the executive to expand its mission. Within twenty or thirty years, "little" will be defined as anything under seven feet tall, "old" as anything over eighteen, "lady" will include all members of both sexes, and "street" will be defined as any road, railroad, path, or trail.
Am I lying?
