As you point out, a toxic black culture has taken hold, and Leftist teachers bear some responsibility for its perpetuation.
The parents need to be responsible and break the chain. There are few role models and too many drug addicted single mothers raising children who will be just like them. I had a coworker who had worked a short time in his youth as a census worker in rural Alabama. We were talking about how the fatherless black children tended to become wild, feral youths. He recalled filling out forms with a single black mother with many children. She pointed to one of her children proudly and said "He know who his daddy is".
