Double the number of dollars in 7 years, what do you expect? The good news is that the currencies the dollar has been devaluing against are in pretty bad shape as well. Right now most European currencies are overvalued while asian currencies (yen, yuan) are undervalued. The bottom line is that you have to make a lot more money to keep up with the shifts occurring in the global economy. The days of retiring on a million dollars and social security are long gone.
