A group that meets those sky-high requirements recently held a top-secret meeting in New York City.
Behind closed doors on a New York campus, a secret gathering of some of the world's most powerful people; Gates, Buffett, Bloomberg, Winfrey.
Together with others at the meeting, including George Soros, Ted Turner, David Rockefeller, they are worth more than $125 billion dollars.
"To have been in the room and see this meeting of the minds really would have been a fascinating thing," said Matt Miller, Senior Editor, Forbes Magazine.
That much money, that much power around one table. It begs the question. What were they doing? What were they scheming total world domination?
This group -- together for 6 hours -- was talking about charity; education, emergency relief, global health.
"All my friends are philanthropic or they probably wouldn't be my friends," said Michael Bloomberg.
An official at the Gates Foundation told ABCNEWS.COM "the overwhelming reason for the meeting was need - that was the issue that galvanized everyone to participate."
Together they have given away $70 billion since 1996. And with the sagging economy, their help could be just what struggling charities need.
Charities are hurting, if they want someone to speak for all these charities. and if they want philanthropy to be robust in the future in the united states, these are really the people you want to be talking about it," said Miller.
