This data for the graph below is taken from the US Census who’s been tracking household income data going back to 1967. They’ve adjusted everything to current day dollars to allow for meaningful year-to-year comparisons.
The data show a very clear trend. The percentage of households in the lower and middle income groups (blue and orange plots) have decreased from 1967 to 2012 while the percentage of households in the upper income group (gray plot) has grown by a factor of 3x! Lower and middle income households becoming higher income households. The popular narrative says the middle class has been in steady decline for years, and that Washington must do something to help.
Washington, don’t just do something, stand there....please.
