Government operates on an entirely different incentive system than the profit motive which guides hiring and firing in the private sector. The people who actually run government agencies are not there to make a profit, they are not even really there to solve the problem, they are placed there to appear to be solving the problem. They think they are there to advance their careers and to do that they grow their empires. The unions who represent them are certainly not interested in solving the peoples' problems, they are indifferent to them, and seek only to appear to be advancing their rank-and-file's interests which is too often an entirely different matter from actually advancing those interests.
However, virtually all those named have a real and distinct personal interest in avoiding the privatization of their functions which would increase efficiency, decrease costs, and actually tend to solve the problems which justify their existence.
