Have private contractors that take over government functions done such a great job? Krugman says "no", and from what I know, I agree. Think of the private juvenile detention center with the corrupt judges, Blackwater, etc. Come to think of it,are government workers any less skillful & efficient than private sector workers? One wonders.
Perhaps the most important point Krugman makes: the same proposition told over and over again becomes "true" regardless of any factual accuracy to support it. Remember: you must keep your crap detector on 24/7! (Thank you, Neil Postman.)
