There's a version of charter schools which is potentially sound. Non-profits with similar oversight and accountability as the rest of the public school system, and no student skimming. And, of course, limits on compensation for administrators. There are good charter schools in Philadelphia. The biggest "foe" of charter schools in the city was actually the co-founder of one. The point is that even she isn't opposed to the concept, just to the implementation which sucks money out of public schools into the hands of grifters and then leaves the public schools holding the bag when the
grifters run away.
