Where is the evidence that cronyism is a bigger problem than bad teachers? Anecdotally, I think there may be some cronyism in small districts. Anecdotally, I also know that sorry teachers tend to get shuffled around school systems because it's a hassle to fire them, and principals would rather shuffle them off somewhere else than do the paperwork/go to a hearing. Hard to say which is the worse problem. Academic freedom is not the issue here; teachers acknowledge that it's about job security. Bottom line, they want to be harder to fire than people in the private sector. Why is that?
Are you asking why public school teachers would like to keep a job benefit they've had since 1976(?) or why the legislation was passed in the first place?
