As sympathetic as I am to the parents and children for whom public school is a necessity rather than a choice, I don't think she's actually wrong here? Putting her kids in public school won't magically immediately increase funding, reduce student/teacher ratios, improve facilities, get reactionary Texas nonsense away from history curriculums, or otherwise fix whatever problems those schools have. Rather it will mean that more people in that school have the resources to Karen their way into getting the people who can fix those immediate problems to make them a priority, and there's a time lag in how quickly that can be done (assuming parents still care enough to agitate as their kids get older and graduate). And while there are a lot of very good reasons to assume that growing up in a family with those resources has a more immediate impact than which school your kids go to (i.e. her kids are still going to have access and interest in private tutoring, PTA involvement, and a home environment free from the stress of economic precarity and that will benefit them regardless of what school they go to), we still talk as though giving your kid a good education at a good school is the most important single thing you can do to help them be successful. If we're going to talk like going to a bad school is like playing Russian Roulette with your kids, I'm not comfortable with the logic that everyone has a moral duty to play because it reduces each individual's odds of losing, y'know?

Of course, given her proximity to the Ratsphere I'm probably being incredibly charitable and she's actually worried about having her kids spend time too close to genetically inferior races with mathematically-described low IQs or something.
