Cancel public education, it's styled after Prussian techniques to create obedient factory workers.
One either knows something or they don't. If you can add, divide, or count to 10 it becomes obvious without having to make someone do it 20 times as homework. Regardless, the underlying issues with edu in the US won't be fixed by not grading things. It will make it hard to track how well the US educators are doing though (not good). The US spends more per child than anyone else and most of it is spent on administrative costs. More money is isn't the problem. It's that the State has no incentive to give two shits about your kids. Public school is a prison for children and the first place most people encounter institutionalized violence.
