Freedom is the answer. In many of these inner-cities the cost per student is amazing... over $20K in many... approaching $30K in DC.
One can get a pretty good private education for those amounts. Bringing true educational freedom (yes, in some sort of state-regulated environment of course) is the only thing that will allow those who want to be saved (and that is the majority) the ability to break the chains of their educational enslavement.
What we’ve seen elsewhere with the system you’re referencing is that the worst actors stuff their kids in the best schools, and end up ruining it. We’re way too tolerant of little Timmy setting things on fire, as it were. It would require a bureaucracy of sorts that, like it or not, chose winners and losers based on their behavior and had absolute authority to shift students around.
Why let the State regulate competing private education? If a private school took $20,000 a year from a voluntary, paying parent for an education that resulted in a “graduate” who could not read, do math, and was taught degenerate morals, how are they worse off? Isn’t that what government schools do, but with money taken from taxpayers at the point of a gun?
