Richest Companies vs. Richest Individuals

Forbes just released its annual list of the world's wealthiest individuals, with Warren Buffett climbing to the number one spot. Here is the list of largest companies by Market Cap on the S&P 500. Ironically, Warren's company, Berkshire Hathaway is not even in the S&P 500. If it were on the list, it would only rank 12th with a $148 billion market cap.
