The weakness of Prof Mankiw’s argument is not in his conclusion that working will yield less of a return under Obama’s plan than under McCain’s plan. The good professor doesn’t go far enough. The step that the professor should take is to ask WHY WORK AT ALL? The more one’s needs the more one is given by the gummint. Work and you get taxes imposed on you. Don’t work and you receive benefits. Work less and let them give you more. Yes, that’s the trick.
