Our duty as an advanced country is to help those that are not.  I always remember a Paul Martin interview where he made the point that we have to help Africa to develop an economy.  He rightly pointed out if we do not the there will be millions of young African males in 20-30 years with nothing to do but make trouble and war.  
As has been pointed out Germany and  Japan are what they are today because of the generosity of the U.S. after the war.
