Sears: "While the economy is still sour for the vast majority of Americans, and for most of the rest of the world as well, the world's billionaires appear to be doing quite nicely. Forbes published is 24th annual list of the world's richest people today. And, though the stock market crash caused a sharp drop in the number of billionaires from 1,125 in 2008 to just 793 last year, like an endangered species in an ideal environment, their numbers are close to being fully restored.
