A broad range of examples, lots of variety! That’s perfect for gesturing at the overarching idea, lest we blow up conversations focusing on specifics in a narrow set.
3. pretty sure the biggest blocker to changing school times is parents’ work schedules. If the schedules diverge too much parents would have a harder time providing transportation to school and mandating adult supervision at all times. 6. it’s not entirely about relative armament. there is base benefit to being able to get rid of neighbors you don’t like or who are sitting on top of resources you want, independent of whether they pose any military threat to you.
Parents’ work schedules are relevant at elementary school, but not at high school, yet high schools keep the same schedule (as far as I know; probably depends on country and school).
Another few reasons that I’ve heard for what’s opposing later high school start times are 1) due to limited numbers of buses, doing high school later would require the lower schools to be earlier, and parents don’t want their elementary schoolers out before sunrise, and 2) after-school activities like sports would be disrupted, both in an absolute sense (they already sometimes run pretty close to sunset) and a relative sense (a school that moved to a later schedule would either not be able to do sports games with other schools, or would have to have the athletes miss much more school than they already do in order to match the schedules of the other schools). To be clear, I do still think that the cost-benefit is clearly in favor of later starting.
