Why don't I live there, even though the location would be more convenient and has far more nearby parks and businesses, the housing is dirt-cheap, they have better access to public transit than we do, the area's more walkable/bike-able, et c? The schools are bad.
Why are the schools bad? Because people like me (that is, people whose kids have a low-stress life outside of school) won't move there. Digging out of that hole is nearly impossible. It amounts to "gentrify things all to hell" (which just shifts the problem around rather than actually solving it) or "fix huge social and economic problems the US has".
In either case, you can't do much about it by focusing on the schools themselves.
So I think by extending the current system to areas in poverty that do not have an established culture of obedience means we have to either change the system or start beating kids again imo. I vote for the former, obviously.
Even worse, imagine being a child growing up in that environment. Actual fistfights were happening every few hours in school where I grew up.
And yeah, it's a red state. Even the blue areas are red enough to get plenty of obnoxious assholes harassing teachers.
[EDIT] Downvoters: go talk to some teachers about this topic. I'll wait. It may be a while, because they'll have a lot to say.
Credible threats of gang violence on a regular basis. School-wide lockdowns with some regularity due to threats of violence, or violence that has actually occurred. Admin with extremely limited options to deal with any of this, and having to triage their discipline pretty hard, plus having little to no support from home to back any of it up (this is why the stuff in the first paragraph happens constantly—no time or community/parental willpower to deal with it, given the rest of what's going on). Watching the kids suffering from the same shit day after day, plus all the usually-awful stuff they have going on at home, and not being able to do much about it. Seeing kids die or end up in the hospital with alarming regularity. Distressingly young kids plainly high or drunk in class.
Not many people can do that without burning out or giving up and half-assing everything, very quickly.
