Yesterday I published in the Wall Street Journal a column entitled the "Two-Income Tax Trap" which was derived from my earlier post here.

I have received a few emails pointing out that in the column, it is unclear what taxes are included in the percentages listed. To clarify, in the book that provides the figures, the percentages (24% in the 1970s and 33% in the 2000s) refer to the total of all federal, state, and local taxes. But the growth in the tax burden between the two periods is largely a result of the growth in the federal income tax portion of the tax bill and the fact that the wife's income pushes the family into a more progressive tax bracket.
