That makes this the perfect time to do this. There's tons of research out there that early school start times have a negative impact on students' learning, alertness, and well-being. We should be pushing schools back to a 8:30-9:00 AM start time. My high school started at 8:30, which was much better than my sister's 7:00 AM start time, and this was explicitly called out as a plus when my high school was accredited. The reason we don't do this is exactly the reason you mention: for the convenience of adults and the rest of the economy. Children don't get a voice, but corporations do. And that's also what makes this the perfect time to do it, when the future of work is in total disarray, nobody knows how they're going to be handling RTO, and large swaths of America is quitting for remote jobs (or just quitting) anyway.
