While the graph in my previous post compared the Top 0.1 percent in different countries, here I made a direct comparison between the US Top Marginal Tax Rate and the Top 0.1 percent income share since 1913. This time just focusing on the United States. {Click on the graph to take a closer look}
Again the effect by the two World Wars is there but what I wanted to emphasize is the relationship between the share of income going to the very wealthy and the change in the top marginal income tax rate.
The income data can be found on Emmanuel Saez's web site. I found the marginal tax rate for the United States in the SOI Bulletin Historical Table A at the IRS site via truthandpolitics.org
