Therefore, bureaucrats should resign their jobs when a government with bad policies comes into power.
C) Giving antimalaria bed nets away for free might seem better than forcing very poor families to pay for the nets, but giving them away for free leads people to neglect them or use them for other purposes. Therefore, it is better to require that even very poor families pay for the nets.
D) Since Katy like princess cake more than David does, it would create more happiness overall if Katy took most of the cake. Still, it would be wrong for Katy to do that because it would be unfair.
