Top philanthropists include Jamsetji Tata (donated $102.4 billion), Bill and Melinda Gates ($75.8 billion), Warren Buffett (is pledging to donate 99% of his wealth). Andrew Carnegie gave away 85% of his wealth -- including construction of over 2,500 public libraries.
Carnegie did that to white wash his public opinion while he worked his workers non stop and to mutilation or death. When are you going to the library when you work 996 or more?
While I hope Warren Buffet isn't cut from the same cloth, the odds are looking quite bad. It would be nice to know there are some out there who can just be smart, get rich, and then NOT damn your immortal soul. But it's looking grim.
Only one billionaire has ever given away enough money while he was alive to not be a billionaire. Ever. Pledges don't count. Also Warren Buffet giving away 99% of his wealth still keeps him a billionaire.
