When I first saw the Mark Zuckerberg “Wealth-o-Meter” in The Wall Street Journal, I briefly felt sorry for him. He has lost nearly $10 billion in paper wealth over a matter of weeks since Facebook started selling its stock to the public.

But then I remembered that the Facebook founder and CEO is still worth about $10 BILLION!!! That’s plenty of money for plenty of people over plenty of lifetimes. Even if Facebook stock continues to dive, Zuckerberg wouldn’t have to work another day in his life if he chose to sell it all.
