Response to the Piketty/Saez Claim of Rising US Inequality.

Below is a response to the Piketty/Saez Claim of Rising US Inequality.

Thanks to a study in the Southern Economic Journal, we know what the picture looks like when the missing data are filled in. Economists Philip Armour and Richard V. Burkhauser of Cornell University and Jeff Larrimore of Congress’s Joint Committee on Taxation expanded the Piketty-Saez income measure using census data to account for all public and private in-kind benefits, taxes, Social Security payments and household size.

The result is dramatic. The bottom quintile of Americans experienced a 31% increase in income from 1979 to 2007 instead of a 33% decline that is found using a Piketty-Saez market-income measure alone. The income of the second quintile, often referred to as the working class, rose by 32%, not 0.7%. The income of the middle quintile, America’s middle class, increased by 37%, not 2.2%.

By omitting Social Security, Medicare and Medicaid, the Piketty-Saez study renders most older Americans poor when in reality most have above-average incomes. The exclusion of benefits like employer-provided health insurance, retirement benefits (except when actually paid out in retirement) and capital gains on homes misses much of the income and wealth of middle- and upper-middle income families.
