Yesterday Federal Reserve Chief Ben Bernanke laid out the Fed's new economic stimulus plan. It's round 3 of so-called quantitative easing, and the Fed will buy $40 billion worth of mortgage-backed securities every month. A year ago Monday, a group of protestors gathered in lower Manhattan, kicking off what would become the global phenomenon of Occupy Wall Street. Occupy raised a surprising pile of money -- but how was it spent? And it used to be, if you ordered something off the Internet, you didn't have to pay state sales tax. But now Amazon is now charging sales tax in a growing number of states; California goes on that list this weekend.
