Bear in mind, those are averages. Don't be surprised if you are much worse off because of distributional skew (huge wage increases at the high end pull the average up).
Moreover, the above chart does not reflect sales taxes, property taxes, state income taxes, gasoline taxes, fees, etc., all of which are way higher now than in 2000. In other words, the chart reflects average hourly wages, not spendable income.
