Since I own a business in the dental field and my sister-in-law is very active in the profession, this happens more than you think. I know of numerous stories in the DC area and in WV area of the system being ripped off and covered up by other dentist. I know of one office in the suburbs of DC where the dentist got busted for stealing millions, went to jail, they took his Md license but never checked to see if he had any other active license. He maintained his DC license and is now out practicing in DC.
Bottomline, it's what happens when government is asked to run anything. Remember, the government employee gets paid for showing up not doing the work. Obama is a great example of this. Every morning he walks into the Oval office and shouts "present" when Soros calls the role.
