Bill Gates pledged to give away half his fortune and persuaded Warren Buffet to do the same. In 2010,  the duo started The Giving Pledge  to sign up other billionaires to their cause.

In 2010 Gates’s net worth was $54 billion, and Buffet’s $45 billion. In 2015, today, Gates’s net worth is $79.2 billion, and Buffet’s $71.3 billion. Way to go, Bill and Warren. You prove that great generosity garners great rewards.
