Why We Need Actual Public Schools

Apparently, California's charter schools have decided to exempt themselves from Transitional Kindergarten requirements.

Can we stop hearing all about how charters do everything public schools do except better on less money?  They don't do it better, they don't do it cheaper, and in this case, they don't do it at all.  Whether it's failing charter schools retaining their charters or outright refusal to follow the law, whatever charter schools are, they aren't public schools.
