Wealthy Americans Urged to Give Billions to Charitable Causes

America’s richest people should commit at least 50 percent of their net worth to charity, three of the nation’s wealthiest citizens said today.

Warren Buffett, who has committed 99 percent of his fortune to charity, along with Bill and Melinda Gates, who have given more than $28-billion to their foundation and say they plan to give a significant portion of their remaining wealth to good causes, issued the pledge.
