I don’t know, but I live in LA, and every teacher I’ve ever known does lots of whining about how they’re not paid enough, and they also complain that all the time off they get isn’t enough, either.
That's life in a bubble. I've lived in D.C. for over 30 years. Many of the GS'ers talk the same way. A lot of them are reasonably sensible people when you call them on it and force a discussion, but the complaint about pay is the default setting. It comes of spending most of their time in a closed environment where no one questions the party line.
I try to stay civil, but it can be a challenge. I used to interact occasionally with an approximately 40 year old GS 15 with a spouse making comparable or more money, with a combined family income north of $250,000, who simply could not comprehend that she was in the top two percent. She lived in an upscale neighborhood where all the houses were in the same price range, so she considered herself average. As a GS 15, she interacted at work largely with other senior managers, SES types, and politicals, and managed to overlook the vast majority of fellow federales, including the people she supervised, who were making much less. Bubble mentality.
