Inspite of data indicating that the US economy has been modestly rebounding, there is a growing fear that it is simply a lull on the way to worse times ahead. That fear, rooted in history, is the product of both legitimate concern and ugly political opportunism. For now, the sea of data is sending mixed signals: on the negative side employment is weak and showing few signs of strengthening, consumers are spending at a reduced pace, states are facing severe budget problems and credit remains tight. On the plus side, corporate earnings are soaring, job loss has slowed, production and productivity are up, the financial system has stabilized, and GDP has been expanding for almost a year.
