It is the job of the:
1. school district to provide the buildings, materials and teachers
2. teachers to provide the supervision, necessary examples and feedback
3. students to provide the necessary attention and effort.
Students whose culture disdains academic achievement as being "too white" will fail and drag down their peers who attempt to excel. Poor impulse control and violent behavior directed against students and staff is condoned. Attempts to punish the bad behavior are characterized as "disproportionately impacting the minority students involved in the acts". It's disproportionate because the white students aren't doing it, thus have no reason to face disciplinary action. Behavior that is allowed and not punished will continue...and it does. The consequence is that good staff exit the classroom for safer places to work. The staff that remain tolerate the abuse because they can't find work elsewhere.
