In the late 70s my father was friends with Howard Jarvis, co-author of Prop. 13 for property taxes, in California.
My Jarvis was not a politician, but instead an older successful businessman. He had watched government grow bigger and more costly, mainly by inertia and lack of constraints.
One thing he told my father, was how career government employees become entrenched, beyond the means for elected representatives to touch.
An example given was that the President had direct power over fewer than 1,000 political appointments. Soon Reagan was elected, in keeping with the taxpayer movement of the 1970s, which Jarvis led.
