Yes.
So much of being regulated comes down to good habits.
Parenting now, and school as well, don't seem to see any reason to develop good habits. Habits of getting along with others, habits that make learning easier, habits of listening to adults in charge without disputing.
It makes everything harder, for the people around the child, but also for the individual child.
Screens are also a huge factor. 50 years from now we will look at giving them to kids as we would giving them cigarettes. But for now, they have them all the time, and worse, many schools entourage them to spend more time on them during school hours.
That all being said - of course some kids are just little shits, where do shitty adults come from if not shitty kids. Some people are just not nice, or they are selfish, or they are psychopaths.
I have spent a lot of time with kids in different environments, including the classroom. Certainly education needs reform, plenty of people should probably be in apprenticeships much sooner.
But also, some kids are bad because they want to be. My partner was a delinquent as a kid. He behaved at home because he had a very strict immigrant mother. Outside, he did about every bad thing possible. Why? Mainly, he liked the excitement. He liked the money, and at that age saw no issues with taking it from people who he saw as unimportant or jerks, but mainly he liked the thrill of being chased by the police or getting in a fight or carrying an illegal weapon. It wasn't until he was much older he saw the larger consequences of his actions and how they impacted society.
