That, and their abusive practices is what makes them criminal.
So long as our society, in general, believes that punishment is an effective form of behavioral modification we are fucked. It isn't.
The way to deal with teenagers who believe they know everything and can support themselves is to provide them with reasonably safe opportunities to prove it.
Our society should provide opportunities like that for children whose parents can't manage it.
As a parent once you've gotten yourself into a power struggle with your teen you've lost. If you feel you have to hire someone to kidnap your teen in the middle of the night, you've lost big.
Two of my siblings ran away from home at sixteen with highly dramatic exits, which is a family tradition, going back centuries as I discern. Fuck you mom and dad, what do you know? All four of my grandparents were like that. But channels of communication always remained open.
Myself, I put my parents through a worse hell, no channels of communication open, leaving them to assume I was taking care of myself which wasn't true in any way. I was learning how to be a feral human dumpster diving for food some days. But I'd long trained my parents, since I was first a psychotic teenager, not to ask whenever I showed up on their doorstep battered and bloody.
What made all the difference was they accepted me, simple food and shelter at first, especially when I wasn't talking.
When I was 12 years old I knew fucking everything, all the secrets of humanity and the universe. With puberty my mind went completely sideways and I didn't gather most of it back together until I was 25 at least.
I think all we humans are the same to some greater of lesser extent.
