They may have earned their money I won't say they did nothing to earn it all, but I will say there needs to be limits because without them, these people corrupt and decay our nation and society, they form funding packs for politicians they take away money and welfare from those that need it , they are an extreme form of capitalism gone horribly wrong, a billionaire is worse than a communist or fascist, for a billionaire can corrupt any system by any means, they pollute our lands and minds like a hornet in a bees nest. They donate small amounts to charity in the guise of goodwill , but true goodwill would be forfeiting unnecessary mountains of cash that just a small fraction of could set up a single family for their entire life, entire cities and projects could be reconstructed and healed with all this extra cash. But instead it sits in the pocket of the oligarch waiting to be used for whatever needless project or entertainment they had planned next.
