My current job involves stopping fraud, waste and abuse in one of the programs that you mentioned.

No one really knows how much of fraud is going on - but, I can tell you that we use fairly sophisticated programs that catch folks scamming the system. Everyday, I get several e-mails identifying people who have made plea agreements or were convicted of fraud. These e-mails only reflect what is going on in my region of the country. The convictions rarely makes the news - but, it is happening - everyday.

I'm sure that some Federal agencies do a better job than others. I just know that my agency is very aggressive in rooting out scammers and folks are held to account for their bad decisions.
