But this idea that bureaucrats -- very broadly defined -- can become their own class bent on protecting their interests at the expense of the public seems not only plausible but obviously true.

The evidence is everywhere. Every day it seems there’s another story about teachers’ unions using their stranglehold on public schools to reward themselves at the expense of children. School-choice programs and even public charter schools are under vicious attack, not because they are bad at educating children but because they’re good at it. Specifically, they are good at it because they don’t have to abide by rules aimed at protecting government workers at the expense of students.

The Veterans Affairs scandal can be boiled down to the fact that VA employees are the agency’s most important constituency. The Phoenix VA health-care system created secret waiting lists where patients languished and even died, while the administrator paid out almost $10 million in bonuses to VA employees over the last three years.

Working for the federal government simply isn’t like working for the private sector. Government employees are essentially unfireable.
