History has shown time and time again that societies can only survive if the difference between the rich and poor stays within certain bounds. The French revolution didn't happen because people were thrilled by the prospects of a democratic system. It happened because the difference between the aristocracy and the peasants grew so large that a few years with a poor harvest were reason enough to topple the whole state. And there are countless other examples in history. If a society wants to survive and remain stable some of the benefits rich people have must also be accessible to the general public (for example health care and education), otherwise social unrest is inevitable (remember occupy wall street?). This does not equate to communism. Neither does it mean that everything is ok just because nobody is starving anymore.
