I'm not in support of teachers in general, but most of the teachers in these communities can't do shit about it. They're literally not allowed to fail more than a certain percent of their class, especially nowadays, so even the kids who never show up are given Cs, Ds, whatever. The kids pass even though they didn't show up that semester and now they're the next teachers problem. The teachers can't control the kids who do show up either, they just fuck off on their phones or fight each other, so if a kid does want to try to learn they don't have a chance either.
