They donated 25 million to the hospital O'Donnell was treated at. 25 million to the United Negro College Fund and 100 million to another hospital in NYC. That's 150 million and they aren't humanitarians? You probably haven't donated 150 dollars in your lifetime.
Trying to undermine American politics and destroy regulatory authority and social programs is causing more harm than any real good they are doing for the sole purpose to appear less monstrously callous. They are not good people and nothing short of disposing of their wealth can fix that.

This free nation has existed for over 200 years because some people succeeded in undermining British politics. If I recall, the driving issue was taxation without representation.
