The real scandal is that NOBODY ever gets fired in the DC bureaucracy! The great Jack Welch, former CEO of GE, would famously demand of his managers that the cull out the lowest 10-20% of performer each year, arguing that there is always a bell-curve, and that there always are sub-par performers (by definition). Only in government bureaucracies does incompetence get rewarded again and again by that blind eye of neglect.
My old firm did exactly that, and I'm sure we were not alone.
