I have a big question

I asked a question about why is it that we get homework after were at school for 7 hours a day and we get homework from almost all 7 classes because most of us don't have the time to do the homework like having to work deal with family drama or even just running around and doing chores for there parents like going to the stores cleaning the house cutting the grass pulling weeds. and then just to do homework after not leaving them any time to do there homework which causes them to go to bed late and then waking up early to do it again and not have time to go out with friends and enjoy life but just doing homework when they could be doing something more creative with their life rather then being isolated writing essays doing history homework, math homework, and so on it never stops till were either on vacation or were done with school but even then you go to collage for another 4 years and repeat the same process and its like it never ends.
