If that is true then I dont have problem with that so far they made their money and they are not stooping anyone from making his own. If you are not comfortable with their wealth go make your own. Rich people to me didn't get rich by default its a calculated attempt to become rich and stay as such... Although I will agree that government will play enough role to make them richer than majority of us but still same I still believe they are richer than that because a lot of people in the other category, they are the source of their wealth if they are billionaires, I am sure they would have created thousands of millionaires and gradually the gap will reduce the more and finally, if they decide not to be rich, I am sure someone else is ready to take their place immediately.
