You do realize that most of the school's money is not spent on administration, right? You do realize that, and this changes from state to state, schools spend so much more money on teachers and their various benefits than they do on administrator salaries, right?
My mother is a superintendent of a town with 5,000 people. While she's not quite to six figures yet, she's not too far off. But what people don't realize is the amount of responsibility which falls on a superintendent's shoulders. They don't see the nonsense they have to deal with, so many of them are not around to realize that when something happens at the school at 2 o'clock on a Sunday morning, the superintendent is responsible for getting up and driving to the school to take care of it. People don't realize how school funding works, how many conferences they have to go to, how many laws they are responsible for knowing in order to not break, etc. People don't know how much it costs to get to the position, how much time and energy has to be put into it, how administration works year round and is on call 24/7, even on their vacation. People don't realize how much money so many of these administrators donate from their own pocketbooks, to help various projects around the school. I know my mom, for example, has donated over a thousand dollars in one year, just for various clubs and programs around the school. She's donated user of her personal belongings for the betterment of the school. People don't realize these things, which is understandable because most people are not around administrators in a personal setting, but that doesn't make their comments any less silly when I read them.
School administrators don't show up at 7:30 and leave at 3:30. They don't work just five days a week. They never get a chance to "be away from it all". I'm not denying there are many many public schools and public school administrators who are not good at what they do. Just like in any profession, you're going to have incompetents. It's just a fact of life. But what also is a fact of life is there are many more administrators who are hard working individuals, who do the job they do because they love kids and are willing to go through the stress, the hassle, the "never seeing family", etc. that it takes to be a school administrator.
Most schools are accountable for their spending. Most schools have to work very hard to make sure their spending is responsible, and meets the numerous guidelines which are tied to nearly every cent that comes into the school. I would suggest you spend some more time with a responsible and hard working superintendent, and see just how much they really do. Then tell me they don't deserve what they make, and that they are not accountable for what they do.
