Why do we need to have public schools?
There is widespread agreement that the DPS system is broken. I say disestablish them. Let people take the money and go out of district, or to charters, or to private or parochial schools. I claim this would be more attractive to middle-class parents than any plausible improvement to the DPS.
I have nothing at all against public schools, but the ones in Detroit have such huge problems of credibility and governance that I don't think they can be fixed in a reasonable amount of time.
