America badly needs corporate tax reform.
The United States pretends to tax corporations heavily. But those heavy tax rates are perforated by randomly generous rules such that many tax-efficient firms pay nothing at all, or even receive money back from the U.S. Treasury. The result is heavy unfairness between industries and firms, an unfairness that many economists believe systematically distorts investment decisions. U.S. productivity growth has been sluggish since the Great Recession—and had actually turned negative by the beginning of 2016.
At the same time, the corporate share of the federal-tax burden has dwindled over the years and decades. More and more of the cost of government now falls upon the payroll tax, which weighs most heavily on low- and middle-income wage earners. These Americans are suffering stagnating incomes, very probably because of the poor productivity growth of the past half-decade.
