Tragic.
What is going on inside the heads of the teachers and administrators at this school?
I feel like there might be a strong, I don't know, social contagion of apathy among the students? Like I get it, I've been there, if you're surrounded by peers who aren't invested and don't care you're less likely to be invested yourself. And the parents, they're struggling to barely provide for their kids, they don't have the emotional/mental energy to keep up on their kid's algebra homework or whatever. It sucks. Are the teachers tearing themselves apart every night seeing how their students are being failed, or have they also fallen victim to the same mindset as the students, where this is just the way things are?
I don't know what the solution is. I doubt it's as simple as more funding. Might involve integration of sorts? I don't mean strictly racial, but, like, funding aside (btw property tax based school funding is a menace, but we all know that)... it's probably not great to have "rich schools" where most/all the students are well-off and are planning for college and have parents who go to PTA meetings and support their extracurriculars and "poor schools" where literally everyone is from below the poverty line with parents working 3 jobs to make ends meet if they have a job at all. Fuck, even if you get the kids to attend the same school they'll probably end up self-segregating along those lines but at least there would be more of a chance? I don't know. I might be off-base, this is not something I've researched thoroughly or at all, really. Concentrated poverty is devastating. Give poor people more money.
I don't know about American situation specifically but concerning the teachers/staff it's probably in general not a mindset, but a resources issue.
Faced with a tough decision, many decide to focus their extremely limited means to aid a small number of students.
The alternative is to spread your efforts, resulting in completely ineffectiveness to help anyone in a meaningful way.
It's hard for people who have not spent time in environments like this to imagine this reality. The teachers or the student's are not the issue, these systems are broken and it breaks people.
