In a speech at the just-concluded G20 summit in London, President Obama urged Americans not to let their fears crimp their spending. It would be unwise, he argued, for Americans to let the fear of job loss, lack of savings, unpaid bills, credit card debt or student loans deter them from making major purchases. According to the president, 'we must spend now as an investment for the future'....instead of saving for the future, we must spend for the future.
