Just how worried should you be about the economy? Federal Reserve Chairman Ben Bernanke himself showed up at a Cal symposium to say: pretty damn worried. According to the Daily Californian, Bernanke diagnosed the problem as financial institutions offering too many loans, underrating the amount of risk in the loans, and relying on financial instruments that no one understood but gave a false sense of security. (Thanks, Ben. We got that already.) Bernanke added that he wasn't sure what to do next. Cal prof Barry Eichengreen added to the party by predicting the recession will last two years. Message: grad school's looking better and better.
