For the "self-interest produces efficiency" people: Here is a payout diagram for the two-player antisocial/prosocial game: (A,A)=(6,6) (A,P)=(15,5) (P,A)=(5,15) (P,P)=(12.5, 12.5) The unique Nash equilibrium is (A,A). That is the United States right now. Please carefully read Adam Smith [1] before making arguments about incentives and efficiency.
