The New York Times' Real Time Economics blog provides a handy-dandy calculator to help you determine where you stand in the United States income spectrum.  Spurred by the whole Occupy Wall Street "We are the 99%" this calculator allows you to input your annual household income and see what percentile you fall under.  Personally I hope I'm graded on a curve.  I, like Ed, like to think that I'm worth more than I make, or for that matter, more than my kids think I'm worth.
