From what I've seen tutoring, homework is more beneficial for elementary students than it is for teens. With the youngest students, we're reinforcing the most basic concepts, like counting, adding, subtracting, reading etc. That only gets better through practice, no way around it, and eventually in life, you need to know how to count and add. But with the older kids I tutor, the teachers shove a ton of homework at them, they rotely copy answers from the textbook, and memorize information only long enough to pass a test. I teach grade 12 kids vectors, they do their test, and then 2 weeks later none of them remember how to find the equation of a plane. Because they can't see why it's important, and have no reason to retain such knowledge.
