That they are, but only to say 'I created 50k jobs; re-elect me.'
To me, that's not much as an incentive but a plea for holding power. At the end of the day the public servants have limited time to make things happen. Companies don't.
If you go buy a new car, you haggle with the dealer. That's just something you do. You have total control to walk out (you have more power,) and you wanted the new car (initiated.)
Yes the dealer will be upset that you haggled, but they still get paid commission, even at a reduced rate. You go home happy, because you got what you wanted, the dealer is happy to have gotten something over their competitor (and the money doesn't hurt); win-win.
