If the water you drink is having problems, you'd have campaigns over it, protests, people trying to get it resolved and potentially lawsuits. People would band together to do whatever they could to fix the problem that they see.
Education is seeing the exact same thing. Parents see a lot of problems. They are going to school board and council meetings, people are campaigning on solving the issue and people are taking whatever measures are in their power to fix it...like home schooling.
When people see problems, they want to fix them. It's exactly the same thing.
