Philanthropy

If multi-billionaires decide to "give" away money rest assured they are not losing anything.
For instance, I consider Monsanto in the top tier of evil-doers.
The Gates Foundation is in bed with Monsanto.
If multi-billionaires cared about humanity they certainly missed plenty of opportunities on their way to power; in other words, the people who care about the quality of life on earth for all creatures including Man never become multi-billionaires as they pay their workers decently, and do their philanthropy on the way up.
Filthy rich people should be deeply ashamed.
