Is Davos 2011 the greatest concentration of wealth in history?

According to Forbes magazine, 69 billionaires from 20 nations are scheduled to attend the economic forum in the Swiss ski resort. By Forbes’ calculations, the assembled elites have a total net worth of $427-billion, greater than the aggregate GDP of Israel and Egypt combined.

The U.S. leads the parade of well-heeled attendees, with twenty, a great many of them affiliated with the spheres of finance, technology and hedge funds. The deep-pocketed Americans include Hedge Fund managers George Soros, Steven A. Cohen and Louis Bacon; private equity bosses Stephen Schwarzmann and Henry Kravis, and tech stars like Google’s Sergey Brin and Eric Schmidt. (However, recent press reports indicate Rupert Murdoch may skip Davos).

Following in second place is India, with 17 attendees, including Mukesh Ambani and Lakshmi Mittal, the two wealthiest residents of the country.

Russia comes in third, with nine billionaires in attendance (although one prominent Russian executive, oil boss Mikhail Khodorkovsky, cannot attend since he is in jail).

Interestingly, there will only be one Chinese billionaire attending and she is a woman -- Zhang Xin, the 45-year-old CEO of SOHO China, the largest real estate developer in Beijing.
