"Republicans say higher taxes on the wealthy kill jobs. In 2001, George W. Bush spearheaded the largest tax reduction in U.S. history (overwhelmingly benefiting our wealthiest citizens) and unemployment rates quickly spiked higher and have remained nearly double the Clinton era levels to this day.
When were the golden years of U.S. full employment? How about the 1960s when the highest earners paid up to 91 percent in taxes? How about the Clinton years (4 percent unemployment) when the wealthy paid 36 percent in taxes (the level President Barack Obama wants to again be the highest rate)? Small businesses hire more workers when demand for their goods and services increase, not when their tax rates decrease."

"Nevertheless, looking at the raw correlation between top marginal tax rates and growth can be helpful for getting a rough sense of the likely impacts of higher taxation on growth. One recent paper by Pikkety, Saez, and Stantcheva looks at the correlation between top marginal tax rates and growth and finds the growth is higher when top marginal tax rates are higher. I restrict myself to the historical experience of the United States and go back to 1930. In particular, I took real chained per capita GDP growth from 1930 to the present from the Bureau of Economic Analysis' (BEA) website. The correlation over this period between the top marginal tax rate and output growth is strong and positive as can be seen below:
A rise in the top marginal tax rate from 0 to 100 percent is correlated with a rise in per capita growth of 5.85 percentage points per year. One reason that this simple correlation might overstate the impact of the marginal tax rate on growth is that the top growth years were in the early 40s when the government was spending heavily and when the country was finally recovering from the Great Depression. If we look only at the post war period (after 1946), a rise from 0 to 100 percent in the top marginal tax rate is associated with an increase of only 2.69 percentage points of growth. Moreover, the statistical significance of the relationship becomes marginal, as the p-value rises from 0.017 to 0.122. On the other hand, if we look at the time period encompassing 1960 to the present, a rise in the top rate from 0 to 100 percent is correlated with a rise in per capita growth of 3.03 percentage points of growth per year, and the relationship becomes more statistically significant (with a p-value of 0.064 percent). Finally, if we look only at the years since 1980, a rise from 0 to 100 percent in the top marginal tax rate is associated with an increase in growth of 3.87 percentage points. In this case, the relationship is statistically insignificant (with a p-value of 0.392 percent), in part because the sample size is small.
While we cannot say that there is a robust significant positive relationship between tax rates and growth, it is still interesting that regardless of when we start the sample, higher top marginal tax rates are associated with higher not lower growth. Moreover, a narrative reading of postwar US economic history leads to the same conclusion. The period of highest growth in the United States was in the post-war era when top marginal tax rates were 94% (under President Truman) and 91% (through 1963). As top marginal rates dropped, so did growth. Moreover, except for 1984, a recovery year, the highest per capita growth rates since 1980 were all in the late 1990s, after the top marginal tax rate had been increased from 28% under President Reagan to 31% under the first President Bush and then 39.6% under President Clinton. One possible reaction to this finding is that what matters more than the top marginal tax rate on income is the capital gains tax rate but growth has also been higher when the capital gains tax rate has been higher."
