This is not because someone "screwed up" or because the government is inefficient. This nothing more than stealing. It is people in high positions using their power to reward no-bid contracts to these companies. The same thing is going on in Iraq where the military claims they cannot account for more than $9 billion. And the Pentagon as a whole claimed to have lost $2.3 trillion (yes trillion) over the last 15 years in an audit done a couple of years ago. They simply do not know what happened to the money.
