I’m a father of three. I’ve had my kids in schools in four different cities. If we’re playing anecdotes, growing up my elementary school started at 8:00. My kid’s have had school start around 7:45. I don’t think that 15 minutes is the issue.

Continuing our story time, as a child a very small number of my classmates were part of after-school programs. Kids today are much more scheduled and for far later into the day. I grew up wandering the streets and maybe had baseball practice one day a week with a game on Saturday. I was home from school around 3:30, had homework done by 4:30-5:00, ate dinner around 5:30, and was put to bed (in elementary school) by 8.

I remember the thrill of having my bed time pushed to 9 around 8th grade. Bed time was 10 in high school except for weekends.

Very few people rode the bus to school: most had a parent drop them off.

This game changes significantly when both parents work. If both parents have to be in the office by 8, kids have to take the bus. Which means they have to get up very early. If both parents work until 5, then kids have to be in after-school programs. They’ll get home by 6-ish and have to fit in dinner, homework, and whatever activities they need to put on their resume to get into college.
