I had the same experience as you. My hypothesis is that all the nonsense about kids needing 12 hours of sleep/"more than adults"/early bedtime is just that, started by parents who wanted some time to themselves at night and perpetuated through convention. Our kids started sleeping, waking up and generally behaving better once we stopped enforcing arbitrary bedtimes.
