(your answer has to be from 0 to 7, ...)
No, it doesn't. Any answer would be different for each individual student, and would depend on their circumstances, goals, ambitions, and abilities. Your focus isn't on achieving one's full potential, but making sure everyone can be lazy enough to make you feel less badly about yourself.
So, for some kids you would recommend depriving of them of sleep, in order to spend more than 7 hours a day on homework?
Which kids? Where do they live? What is their family situation? What school do they attend? What are their goals? What are their abilities and aptitudes? What are their goals? What factors are likely to advance or impede those goals? Etc, etc.
Sorry comrade dimwit, it's just not as simple as you want it to be to justify your own shortcomings.
It was an open ended question. You can fill those in in your answer.
But instead, you refuse to answer, generally speaking, or more specifically speaking, or even an single individual anecdotal example.
You refuse to put any limits on the amount of work that could be put on a child, yet viciously attack me, for daring to suggest that too much work could ruin a child's life.
That is not rational of you. You are consumed by blind ideological commitment to MOAR work, without any thought to the cost.
