If there's a silver lining for Joe Sixpack in these difficult times, it's the spectacle of watching the uber-wealthy lose tons of money. Forbes has obligingly recalculated its list of the 400 wealthiest Americans to account for the recent economic struggles. Sadly, there's no schadenfreude at the top: Economy-unto-himself Warren Buffett actually increased his net worth by $8 billion in September—knocking Bill Gates out of the No. 1 spot for the first time in 15 years. His total now stands at $58 billion. At the other end of the spectrum, Las Vegas Sands Corp. CEO Sheldon Adelson lost $4 billion. Sergey Brin, Larry Page, Carl Icahn, Jeffrey Bezos, and Gates are among those who lost over a billion.
