Citizens hold their government to a higher standard. As an analogy, the government can't just go to the hardware store to buy a hammer. It needs to buy a hammer from an American using a drawn out bidding process that preferences veterans and minorities, etc etc. Iterate this for evey little thing.
That isn't fraud or corruption as most folks understand those terms. It is more simply not designing for efficiency. People are more concerned with other factors like fairness transparent process.
