I think 2 hours would probably be plenty. I've seen schools during the pandemic have about 1 hour of teacher/student of subject instruction, and that's with larger cohort sizes (9-10 students) and doing everything virtual. You can also look at homeschool examples, here's one I just randomly found[1]. She spends about 1 hour and 15 minutes actively teaching her 5th grader and 30 minutes with her 4 year old (they also study on their own or sit in with each others classes). As others mentioned, a big part of the issue is that school ends up serving as a daycare for many parents. It's likely that school isn't optimized for education, and there is a good chance that much of school is just for occupying kids that we as a society aren't willing to accommodate in any other way.
