The Newsweek 50: Fiscal Wise Man Warren Buffet

As the titans of American finance toppled over this fall, Warren Buffett stood tall as one of the few forces of order in the private sector. The 78-year-old Nebraskan injected $8 billion into two icons: investment bank Goldman Sachs and General Electric, which he dubbed "the symbol of American business to the world." Buffett (a member of The Washington Post Company's board) didn't do it for the health of the system; the investments carry hefty 10 percent rates. But as America works to pull itself out of recession, Buffett and the values he champions —buying assets on the cheap, discipline, a long-term view—will be at the forefront.
