When an individual has more money than the GNP of many countries, he or she has WAY too much money. It serves no purpose other than bragging rights to fellow filthy rich.
That money came from someplace, and that someplace was from the 99.9 percent because they have to make up the difference so these parasites can live better. The money came from tax policies granted to them by the politicians they own or else they have outright stolen it from their employees through low wages and few or no benefits.
The parasites in turn can continue to buy the politicians and even public opinion in order to preserve the wealth they stole from everybody else.
