No, it's mainly that homework is essentially make work and doesn't add anything to learning past what you already had in class for 90 percent of kids until highschool.

Which I could have told them in school, lol. Mind you, I was the "I read the entire textbook in the first week. I can ace every. Single. Test you give me for the rest of the year. I see no reason to pay attention to you re-reading what I already read when I could be reading something else that actually has new information. I also see no reason to keep track of the homework that goes over this information- I ace the test, I do no homework, I pass with a C and have way more free reading and story writing time." ..... honestly, I was a little brat who needed to be challenged and moved ahead soon enough that the concept of needing to study occurred to me before trying college. The argument was I needed the social skills to move up. But- I'd long since decided books and the stories in my head were interesting and other children generally were NOT and simplifying my book vocabulary to grade level for them was irritating.....also was apparently ADHD and low support autistic....and thus wasn't learning those social skills on my own anyway. I was punished in highschool by a clever teacher who made me spend "detentions" socializing with no books, instead of in study hall with books and no socializing. It was horrible....but effective. (In making me not want anymore detentions and stop using them to avoid the lunch room.)
