Who's Watching the Government?

If Obama is going to tell corporate executives how much they can earn, then cap it if it reaches a certain limit, and/or eliminate positions if they or their company is unsuccessful (in the opinion of the President) - then why don't we offer the same criteria to the government? Why don't we cap and/or eliminate government officials when they reach unsatisfactory performance? Barack, I believe as a voter, I'd have you down to minimum wage . . .
