A report from the Congressional Research Service finds little support for the claim that tax cuts increase economic growth. They do, however, increase inequality:
Report: Tax Cuts for Wealthy Linked to Income Inequality, by Siobhan Hughes, WSJ: Just in time for the year-end debate over extending the Bush tax cuts for high earners: a new report concludes that tax cuts for the rich don’t seem to be associated with economic growth.
The report, from the Congressional Research Service, finds that tax cuts for high earners can be linked to a different outcome: income inequality.
“The evidence does not suggest necessarily a relationship between tax policy with regard to the top tax rates and the size of the economic pie, but there may be a relationship to how the economic pie is sliced,” according to the CRS report, circulated on Friday. ...
“As the top tax rates are reduced, the share of income accruing to the top of the income distribution increases; that is, income disparities increase,” government researchers said.
CRS analysts also said that “capital gains and dividends have become a larger share of total income over the past decade and a half while earnings have become a smaller share.” This phenomenon, the researchers said, suggests that labor may grab a larger share of the pie when the top individual and capital-gains tax rates are higher. ...The implication, of course, is that allowing tax cuts to expire for high income individuals could decrease inequality without harming economic growth.
