I think kids should not have bedtimes because it's a good way to show your parents you're responsible enough to wake up in time and go to bed at a reasonable time.
Maybe they have some late homework or some studying, I understand sometimes kids might stay up texting or on their phones or something like that or even TV, but if they don't wake up in time for school, it's on them.
But for kids that have to drive or bike, skateboard, scooter, I recommend going to bed early so you're awake when you're riding, driving!
