In this testimony, Burman summarizes the trends in inequality, examines the role the federal tax system has played in mitigating inequality, and discusses the effect of the tax cuts enacted since 2001. He concludes that while the income tax system provides one mechanism of redistributing the gains of our dynamic free-market economy more equitably, the immediate benefits of the recent tax cuts have accrued disproportionately to those with very high incomes and have undermined tax progressivity. Without knowing how they will be financed, it is impossible to determine how these tax cuts will ultimately affect the distribution of economic burdens in the United States.
