I suspect you're a victim of the toupee effect. You likely don't notice all the kids behaving well. However you explicitly notice those that are being terrors. Because of that, all the kids you remember are hellish crotch goblins.

I have a young daughter. She's very generally very well behaved in public. The few times she's been a hell raiser, I've removed her from public, rapidly. At the same time, I've not raised her to obedience by authority. Instead she is cooperative by mutual respect. It's a lot harder, but seems to help mold a far better little human.

The ones who run riot have often broken their parents. I didn't truly comprehend the pressure a small child can apply, mentally and emotionally. It can grind you down rapidly. You need a comprehensive plan to outthink them, otherwise they will grind you into the ground and YOLO dance on your (emotional) corpse.
