And imagine being the one new excited, passionate teacher trying to rock the boat and get some effort. You're upsetting parents who wonder why you're all up in their business and don't understand the value. Your gradebook creates issues for your administrators. Other teachers who have given up react defensively and seek to undermine you. And the students are not thankful, and can be extremely disruptive.
I don't know how you fix it. Project-based learning has some evidence that it can work in situations like this, because it can draw out participation and interest by gamifying more of education. But it's not like a little more PBL is going to make the system suddenly work.
