>My own conclusion from reading it is that few things really make difference: 1. Charters have strict discipline, violence etc is not tolerated in any form. Public school in bad areas are chaos 2. Schools can easily fire teachers who do not perform well. In public school system you need to rape or murder someone to get fired. 3. Shitty charter schools lose their charter and go out of business

Basically all the same reasons that rent-a-cop type security places never have problems with hot headed jerks the way municipal police departments do.
