Oh yeah, they are rampant in government work. I find it extremely frustrating, but I just try to focus on my responsibilities and try not to get worked up about things I can't control. It's easier said than done.
As a side note, the fact that these people are able to find and keep jobs really makes me question myself. I'm not a rockstar, but I am a competent developer that can get shit done, bring value to the team, and is always trying to learn but I'm having a hard time getting a new job. It's frustrating as hell.
