#5 Media mogul Ted Turner            

Ted Turner is an American media mogul who’s worth more than $2 Billion. As a businessman, he is known as founder of the cable news network CNN, the first 24-hour cable news channel. As a philanthropist, he is known for his $1 billion gift to support the United Nations, which created the United Nations Foundation, a public charity to broaden support for the UN.

Turner has five children from three marriages, but they won’t be inheriting his wealth. Turner was quoted in 2010 as saying he was "almost to the edge of poverty" and just wants enough money to cover funeral expenses when he dies.

#6 Hedge fund manager John Arnold

John Douglas Arnold is an American hedge fund manager, specializing in natural gas trading. He may be only 40 years old, but last October he closed his hedge fund, Centaurus Energy, and retired after amassing an estimated wealth of $4 billion over the last 10 years. Now, Arnold and his wife Laura have dedicated the rest of their lives to giving away that wealth through their foundation to support innovative ideas, instead of to their three children. "Because of our backgrounds and because of our own experiences, we just don't believe in dynastic wealth," said Laura Arnold in an interview posted on givesmart.org.
