Americans have become increasingly critical of public policy as a means of addressing social problems.  Many believe that these policies don’t work; the reality is that public policies are often subverted in ways that make them ineffective or even counterproductive.

Take taxes and inequality.  As Danny Vinik, writing in the New Republic explains:

The vast majority of Americans—both liberals and conservatives—believe that state and local taxes should also be progressive. That’s the finding of a new report released by WalletHub Monday. The researchers surveyed 1,050 Americans on what they thought the combined rate of state and local taxes should be at various income levels. Not surprisingly, liberals want the rate structure to be a bit more progressive than conservatives do, but their responses [as the following chart shows] were relatively similar:

However the reality is quite different.  State and local taxes are actually quite regressive.  The Institute for Taxation and Economic Policy studied the “fairness of state and local tax systems by measuring the state and local taxes that will be paid in 2015 by different [non-elderly] income groups as a share of their incomes.”  They did this state by state and, as presented below, on an overall basis.  As we can see, the lower the income, the greater the state and local tax burden.

Here are some of the report’s key findings:

• Virtually every state tax system is fundamentally unfair, taking a much greater share of income from low- and middle-income families than from wealthy families. The absence of a graduated personal income tax and overreliance on consumption taxes exacerbate this problem.
• In the 10 states with the most regressive tax structures (the Terrible 10) the bottom 20 percent pay up to seven times as much of their income in taxes as their wealthy counterparts. Washington State is the most regressive, followed by Florida, Texas, South Dakota, Illinois, Pennsylvania, Tennessee, Arizona, Kansas, and Indiana.
• Heavy reliance on sales and excise taxes are characteristics of the most regressive state tax systems. Six of the 10 most regressive states derive roughly half to two-thirds of their tax revenue from sales and excise taxes, compared to a national average of roughly one-third . Five of these states do not levy a broad-based personal income tax (four do not have any taxes on personal income and one state only applies its personal income tax to interest and dividends) while four have a personal income tax rate structure that is flat or virtually flat.
• States commended as “low tax” are often high tax states for low-and middle-income families. The 10 states with the highest taxes on the poor are Arizona, Arkansas, Florida, Hawaii, Illinois, Indiana, Pennsylvania, Rhode Island, Texas, and Washington. Seven of these are also among the “terrible ten” because they are not only high tax for the poorest, but low tax for the wealthiest.

In short, we know how to construct tax policies that can lessen inequality, but we’re not using state and local taxes to do it.
