Blaming the parents is not going to improve the situation. The issue is what to do, given such feckless parents, to mitigate their impact, isn't it?
No one is even having the conversation. No one is standing up to the parents and saying, hey the government can't solve all your problems. At a certain point you have to take a break from watching internet pron and read to your kids.
I support BLM but police can't raise your kids or fix your community. Trying to ask them to do that only leads to problems. Same with teachers.
Do you have children? Do you know what it is like to try and get through a lesson plan with a classroom with 20+ children when half of them come from homes where no one cares? At a certain point a teacher is going to focus on the half that pay attention in class and turn in their homework.
