As for whether or not charter school capital ” screws” the “public school system”, consider this: charter schools ARE public schools under the law. It s official. You need to check you ideology at the door, the decision is a matter of law. If charter schools now seek to claim a reasonable share of public funds dedicated to school capital, that is a logical consequence of the fact that they ARE public schools first and foremost. Get over it. Traditional school governance has many failures, and the alternatives (charters) have legal standing. And wide public support. Your brand of school governance is not the only game in town, charters are a viable and attractive alternative deserving of commensurate public support.
The counter attack:
Charter schools are public schools, under the law!
They are also CORPORATIONS, under that same law. They are public in one way only: we finance them because a group of misguided legislators wrote a horrific law in 1995 and have walked away from it.
