Great points, thanks for the reference to that book. I follow Philadelphia District Attorney Larry Krasner[0] and I think he's headed in the right direction. I'm not in Philadelphia but reports of his efforts are very positive.
The reason for me knocking privatization is corruption. Kickbacks/lobbying[1] and nepotism[2]. While most of these actions are legal I don't think it is ethical.
I'll do some more reading before commenting further.
