I learned the hard way that skipping the homework means bombing the test. You don't learn problem solving skills by listening to a lecture or watching TV. It's easy to imagine you've learned it, till you're confronted by the test.
This is true in later education, but it seems to not be so helpful in earlier education. You're far better off with supervised practice than unsupervised, at-home practice in younger students.
The teachers hardly ever filled up the class time, so there was always time to just do the homework.
Typical homework loads today are waaaaaay over 5 minutes per class in MS and HS. Current high school homework loads are on the order of 10 hours per week in many places.
And in fairness, people like you or me, or most of Hacker News-- don't really count. We're outliers and not really predictive of typical experience.
If the school-by-zoom accomplished anything, it gave the parents a window onto what was actually being taught. They didn't like what they saw, hence the pushback in the PTA and school board meetings.
I remember my highschool chem teacher harping on the class after every test "I'd like to tell you all that if you don't do the homework, you won't pass the test, but toast0 didn't do the homework and did the best on the test so do the work" (or something like that). To be fair, I'd look at the homework, I just didn't feel like writing it down and turning it in, most of the time, so for classes where grading let me skip homework and I felt I had a good grasp of the material, I skipped it.
But, for kids like me, we'll succeed im school as long as there aren't active roadblocks from staff (or other students or other life issues). I think the real question is how to help the kids that need help. How do we get them motivated and engaged and empowered to learn the material?
I certainly was not.

I did get some roadblocks from some the staff. I did well in spite of the staff's efforts :-) My biology teacher disliked me (for good reason, I was a jerk), and told me he was going to be very hard on my grades. If an assignment was subjective, he'd give me a bad grade. If it was objective, he was forced to give me As. Fortunately for me, nearly all the assignments and tests were simple checkboxes.
