We're hearing a lot about the economy lately. In fact, just this week, Alan Greenspan actually said "the r word" by announcing that the United States is in a recession. Our last recession, from 2001-2003, was due to the collapse of the dot-com bubble, the September 11th attacks, and accounting scandals such as Enron. There were also recessions in the early 1990s and early 1980s.
