It’s because this is a very simplified view of a classroom. What is presented above is the best case scenario, not a realistic one. For example, there’s no consideration of costs associated with any sort of handicapped student, or student with special education needs.

Real world costs completely spiral out of control when you look at the actual system—for example, the buildings are all built during the rapid expansion of the country so are now old enough to need expensive maintenance, and there isn’t money or interest from the community to tear them down and build new ones.

Also something else that isn’t being covered is that involved parents are pulling their kids out for home schooling, and well behaved kids are increasingly being pulled out and put in charter sschools. This is leading to a rapid collapse of the school system. Public school is being left as a place for students who’s parents don’t care enough to do anything with them, or with enough behavioral or special needs that charter schools won’t handle them.

What kind of maintenance do you think is expensive compared to a budget of $560k per room, per year?
