#6. George Soros: $10 Billion (current total Net Worth $20 billion)
Originally from Hungary, Soros emigrated after WW2 to study at the London School of Economics while surviving as a waiter and railway porter. Soros excelled in the financial field, developing the economic theory of reflexivity, and becoming infamous as ‘The Man Who Broke the Bank of England’ during the 1992 UK currency crises.
Soros has long been a supporter of human rights and open democratic societies. During the 1970s, Soros funded both black students living under South African apartheid, and dissidents behind the iron curtain. He is also credited with being instrumental in the transition from communism to capitalism in Hungary during the 1980s.
In 1993, Soros founded the Open Society Foundation, a public policy grant network that promotes social reform, human rights, and democracy. Among the billions Soros has donated, 1.7 billion has gone to human rights efforts, while another 1.6 billion has gone to education. Source
