My guess is that they are ALL "daddy-less" teens.
Mothers are essential from birth to about twelve. (two required Sociology classes) After that Dads are essential. They are supposed to teach their children what it is to be a MAN, a father, husband, son, etc. Another important task is to teach their children, especially the black children, how to deal with adult authority, especially adult male WHITE authority. No "dad" = no "education" from dad.
The blame lies with "mom" who didn't bother to marry her, er, "first" or any men thereafter. Since the government doles out money for each child, it behooves these sinful males and females to keep breeding, irregardless of the good of the children.
Selfish, immoral/amoral, arrogant and a SURE knowledge of entitlement. It's generational and they fill the prisons.
Wow, I'm amazed you got that from any sort of "contemporary" Sociology class: the acknowledgment that "Dads are essential" [for proper upbringing of children.]
