I think you have hit the nail on the head why more police funding, more surveillance tech, more dystopian BS that looks more like PreCrime every single day, is only going to get us so far.
I'm sure there are exceptions, but I think most folks (including criminals) believe crime is, generally speaking, bad. Folks commit crimes to survive, to enrich themselves, out of retribution, out of lapse of judgment, or lack of self control. Almost all some flavor of unmet needs. You put money into tackling those challenges, address why people are stealing, why turf wars break out, why addiction ruins lives and puts people in terrible positions, why poor nutrition and family support and mental health care lead to so many folks slipping through the cracks.
School quality’s largely in the same place. You’re not going to make much of a dent without fixing social support, the social safety net, healthcare, mental healthcare, and generally greatly improving stability for the economically bottom third or so of families.
In other words, the main problems with schools have little to do with schools. But they’re complicated and expensive problems with distant payoff, so we keep monkeying around with schools instead.
