There's one slow-motion conservative victory happening that's getting relatively little news coverage (and that's a good thing, lest there be more pushback): allowing more alternatives to public schools, funded by taxpayer dollars. Charter schools are the most obvious example, but I expect this to eventually be expanded further. If 10 homeschooler families want to get together and hire a professional teacher, there's no reason why the state shouldn't pay for it (provided the kids pass grade-level standardized tests).

Like you said, 99% of what makes a "good" school good is the quality of the other kids who go there. Since there's absolutely no political will for expelling the troublemakers (even in most conservative districts), the only remaining option is to build more lifeboats.
