I'd rather just stick to what studies find as best instead of anecdotes about needing to physically exhaust children to force them into the desired sleep schedule. Also there's research showing humans have varying natural times they ideally sleep at, and they suffer outside those hours.

That's no joke. I did tree removal for a few weeks one Summer while waiting for my Summer camp counselling job to start. I slept a solid 10 hours every night and felt awesome every morning. "Guiltless sleep of the righteous" and all of that. If they could bottle that sleep in a pill without having to drag downed trees all day, it would be crazy addictive.

Have you read the relevant research on the subject?

Teenagers literally have different sleep rhythms than either children or adults, so in the average case staying up late is a symptom, not a cause.

ITT: people who haven't read the research decide they know what is best based on personal anecdote

> physical labor during the day

You heard it boys and girls, back to ploughing the fields it is!

I'm hearing child labor is coming back in vogue in the US!
