April's been busy for George Soros. The billionaire traveled the world to plug his 10th book. He made headlines calling for tighter regulation of hedge funds. He's also reportedly looking into buying a top Italian soccer club.
To top it off, the 77-year-old still banks billions. Last year, Soros saw opportunity in choppy financial markets and returned to his financial company Soros Fund Management. Forbes estimates his 2007 earnings were $2.4 billion, the second most on Wall Street. We calculate the total net worth of this hedge fund pioneer at $9 billion.
