I'm inclined to believe that.

Either way - publicly-run or private contractor, if the government is a good steward of public funds, they'll monitor well to avoid waste and remove people who are trying to unjustly enrich themselves. And if the officials are incompetent or corrupt themselves, they'll fail to recognize when those things are happen, or participate themselves. I don't see a big difference in public vs. private unless I imagine a fantasy government run only by officials who are smart and highly ethical.
