The rating agency Standard & Poor’s stunned the world a year ago by stripping the U.S. government of its prized AAA bond rating. A year later, S&P’s historic move looks like a non-event. Long-term interest rates are sharply lower, the Dow Jones industrial average has reversed course and is now up more than 1,600 points. The dollar has rallied, and gold prices are down from where they were when S&P lowered the boom (AP Photo/Jacquelyn Martin, File)
