There was a section describing parents whose elementary school kids would have to start earlier, and they didn't like that because the kids would have to go to bed earlier and it would be tough to rearrange their work schedules to accommodate. But won't this also be true when their kids are in high-school? If they can't cope now, how will they cope then?
I always though it was obvious that elementary school and high school start times should just be swapped because in my experience elementary aged kids always wake up far earlier on their own.
