The school system is already that homework exists.

Actually think about that for a second. They have 8 hours with your kid 5 days out of the week, and then (as a parent) you have to help them with the stuff they spent 8 fucking hours on for an additional 2-3 hours at home.

The more you start to understand about education and training, the worse you can see the school system actually is. Even with good teachers, the entire structure is broken.
