That would work like the 'Charter' schools. They'd pluck out all the healthy, intact students and claim great educational results. The reality is, they are comparing their results to public schools who also must include students with special needs, low IQ, hearing impairment, developmental delays, etc., in their data. When you compare apples to apples (i.e., regular education students) the charter schools perform miserably. They privatized prisons in Arizona, as I recall. The prisons then donated to the election campaigns of judges. The result? Said judges give harsher sentences in order to put more money in the hands of the private prisons. The same kind of malfeasance, only worse, would happen if you tried to privatize public schools. It would be a return to segregated schools, among other things. I've worked with many, many teachers. All but a tiny few should probably be considered for sainthood. Along with nurses, they are the finest people our country produces. I don't know where they get the strength, compassion, and sense of self sacrifice.
