I work outside the home- as a teacher- and I see a purpose in homework.
I teach in a great public school, but since I don't live in this district, my kids go to Catholic schools; the schools in my home district are beyond awful. My own children spent grammar school having homework in every subject every night- even if it was simply reading over something. I am lucky that none of my kids have major learning issues, so this was not a burden. My oldest has AS, but since he loves rules and structure this was fine for him. It was the same in 1st-7th grade- the same expectations, the same heading, everything- so he felt very comfortable. My oldest two are now in high school and my youngest is in 7th grade. I don't have to fight with any of them to get homework done; they just do it. We talk a lot about what they are doing in class, etc. Now, my oldest two are NOT straight A kids, nor do I expect them to be. Both have their strengths and weaknesses. I accept Bs and the occasional C, as long as they are not receiving bad grades on homework. Many a night they are doing homework while I am grading papers, so it is family time. They are not shut up in their rooms alone doing it. My youngest has learned so much from having older siblings. All three of the kids play sports, the youngest is in a drama group, etc. We have plenty of time for homework as well as other activities.
The school I teach in is on the 4x4 schedule. Our students have two core classes and two electives (unless they are in honors) each semester. At most, they will have homework in two classes. And I have trouble getting them to do it. I am talking reading one chapter in a book and doing an activity- not always the question thing; I try and include creative activities or give a TicTacToe where they can choose the activity when appropriate. We have a tutoring lab open for free 3days a week after school 2:30-5:30 with busses to take the kids home (I run the English lab on Tuesdays and part of the day on Wednesday). They can go to TLC and then practice if needed. Yet very few of my students complete homework on a regular basis because the middle school model here is no homework and all self esteem building. They are not used to doing any school work outside of school. It is impossible for me to teach what I need in the time allowed without them doing some work at home. Our classic novel has 31 chapters. We cannot read the whole thing at school, yet some students refuse to do any work at home. It is very frustrating to me. Homework should not be 50 math problems or 10 worksheets on grammar etc, but some homework is a good thing. It should be purposeful. It should assess what the kids can do outside of class. But, IMO, it is needed.
