7. The Short-Seller (part I)
David Einhorn
Greenlight Capital

He famously shorted Lehman stock this year, but Einhorn has long worried about the amount of leverage employed by financial companies. He thinks it will be a while before the economy is out of the woods, and to strengthen the financial system he thinks we need to stop relying on credit rating agencies: "They had a responsibility to monitor our largest financial institutions and force them to maintain reasonable leverage ratios or suffer rating downgrades. They failed, and we are all paying."
