I think it's because of the way they're organized. First, they're unionized, which makes it very hard to change them out. It also means that they are always overpaid with lavish benefits, and that innovative teachers are crushed by the group. Even more important is the fact that the curriculum is defined by the state (a very rigid thing, indeed). This means that it's practically impossible to do a good job, even if the teacher doesn't begin his or her career with evil intent. Why should all of us be forced to know all the same things? Isn't diversity in intellectual matters valuable?
