This non-partisan CRS report Initially released on September 14, 2012, the study--authored by Thomas Hungerford who is a specialist in public finance at the C.R.S.--correlated the historical fluctuations of the highest income tax rates and tax rates on capital gains dating back to World War II with the economic growth (or lack of the same) that followed. The report found absolutely no correlation between the top tax rates and economic growth -- thus destroying a key tenet of conservative economic theory. United States Senator and then-Minority Leader Mitch McConnell (R-KY) raised concerns about the methodology and other flaws and the report was taken down by CRS. Senate Democrats later re-published the report.
