Oh wow a necro bump.

The average kid spends just over 1200 hours per year at school. So much of it is wasted doing stuff they will never use in real life.
They keep cramming more and more into the 7 hour/180 day school year. Because of this there isn't enough time to cover everything in class. Kids are forced to do several hours of homework each week on top of their school day. It should be school and then childhood after the bell rings to dismiss. Kids shouldn't have to worry about getting home before bed to get their homework done. It should be covered in class. There would be enough time to cover it in class if they cut out all of the bullshit like diagramming sentences (I hated that too pinwheel).
Imagine how much better the world would be if schools focused more on teaching kids life skills like being respectful, solving disputes, social skills, safety, first aid.....others like cooking, cleaning, hygiene, taking care of kids/pets, home and auto maintenance and self defense. Instead we force kids to sit at a desk and do things they will probably forget.
