Tax progressivity in the US: Do the rich pay more than their fair share? The evidence indicates NO!

Just How Progressive Is the Tax System? – Economix Blog – NYTimes.com

According to a blog post in the New York Times from April 2009, America’s America’s “progressive” tax system is not as progressive as many may believe it to be:

Research has found that many states and local governments have… regressive tax systems… that might offset the progressiveness of [US] federal tax rates.

The research from Citizens for Tax Justice — a liberal organization that advocates “fair taxes for middle and low-income families” — uses 2008 data for all federal, state and local taxes combined. It found that the average effective tax rate is 29.8 percent, and that including state and local taxes makes the tax curve look much less steep:

In the graph above, the horizontal axis shows the income group. The vertical axis shows the percentage of income that the average member of that group pays in taxes. Taxes include all federal, state and local taxes (personal and corporate income, payroll, property, sales, excise, estate, etc.). Incomes include cash income, employer-paid FICA taxes and corporate profits net of taxable dividends.

The article continues:

The group also finds that in 2008 the share of total federal, state and local taxes paid by each income group was relatively close to the share of income that that group brings in, at least as compared to comparable 2006 numbers for effective federal tax rates:

The horizontal axis shows the income group. Taxes include all federal, state and local taxes (personal and corporate income, payroll, property, sales, excise, estate, etc.). Incomes include cash income, employer-paid FICA taxes and corporate profits net of taxable dividends.

The research discussed above poses several interesting questions about the make-up of a nation’s tax revenues. Despite popular belief, it appears that the rich in America do not pay “more than their fair share”, as many argue is the case. Study the graphs carefully, and answer the questions that follow:

Discussion Questions:

  1. Based on the data above, do the rich in America pay an unfair proportion of the total taxes the US government collects? Why or why not?
  2. Why do the richest 5% in America actually pay a lower level of tax on average than the 5% below them?
  3. How much of America’s total income is earned by the richest 1% compared to the poorest 20%? Does America’s progressive tax system destroy the incentive for Americans to work hard and become rich? Why or why not?
  4. Use the data to construct a Lorenz Curve for the United States. Does the gap between the richest and the poorest Americans surprise you? What kinds of changes could be made to the tax system to narrow the gap between the top income earners and the middle and low income earners in America? Should this be done, why or why not?
