Even if you pin the "blame" directly on teachers, they have a difficult situation. They need to get 3-5 classes of 20-40 mostly obnoxious kids to learn a broad array of material prescribed by other people. They have to do this while also correcting behavioral issues and dealing with parents or admins.
They're mostly not domain experts knowledgeable enough to give individualized deep dives to each of their students, but even if they were it would make their already-difficult task impossible. It's a wonder that any sort of individualized instruction manages to exist at all.
