Those people spent their entire lives building their empires at the expense of the little people, screwing everybody that got in their way. Ever see the movie “There Will Be Blood”? That wasn't just typical 100 years ago, it is still typical today. Why the hell did Warren Buffet and Bill Gates wait so damn long to donate 50% of their wealth to charity? Hell, they are both multi-billionaires and had accumulated so much wealth that it would be impossible for their grandchildren’s grandchildren’s grandchildren to spend it all in one lifetime.
Look at J. Paul Getty. That asshat raped and destroyed countless lives in his quest to become a mega-millionaire and waited until his death to bequeath his fortune to a museum. He didn't leave any money to charity. Nope, just built a massive museum and stipulated that his millions and billions of dollars go to acquiring artwork. No soup kitchens, no homeless shelters, no scholarship funds. Just friggin’ artwork.
Warren Buffet can shove it where the sun don't shine. What a maroon.
