I question that statement. Care to elaborate? I can provide examples of how this is not the case.
Just examine the private contractors in our current wars.

I don't think that is a very good example of anything besides how spoiled and pampered our politicians are. Obviously privatizing a massive money losing clusterpuck that only existed as a major perk for politicians had to be an improvement over the status quo.
The fact that the Senate had to do multiple studies to figure out that they should do the same thing the House did decades earlier says volumes about our government and decision makers.
If you search around, there are plenty of case studies, a number of which are in other countries. Corruption of public officials is a central problem, but this has nothing to do with the act of privatising, it is a failure of government. Those same corrupt officials would be running the state run system if it were still intact. You just wouldn't know about the money changing hands.
