I agree that the problem is systemic but it's a bit more complicated than this - the reason why such a high percentage of the students are failing is likely because the parents of the students that wouldn't fail have disproportionately opted out of this school, whether by moving or through charter/private schools, which makes things even more difficult for the school administrators and the teachers. The real systemic issue is that nearly ever competent and rational actor is incentivized to run away from the problem. This applies to parents, teachers and administrators. No one's life gets better by taking this problem head on and making things incrementally better, so the only people who are left to deal with the problem are the ones who don't realize how bad things are, don't care or don't have the means to move away.
