Fraud and corruption. Everyone gets piece of the pie. I said it before... Wars create loopholes for money to disappear. In first 3 months of Iraq invasion half a billion dollars went missing. Where all this money go? Someone pockets, that's where. It started with Bush and continues with Obama.
Many government officials have phony companies on the side that sale poo service and get paid millions for it by our government. Indirect income for government officials, impossible to track.
