This map shows how red states increase inequality and blue states cut it

Vox says This map shows how red states increase inequality and blue states cut it "State and local taxes don't get covered as much as federal ones, but they're still very, very important. Indeed, a new study finds that they can have significant effects on income inequality. Fed researchers Daniel Cooper, Byron Lutz, and Michael Palumbo estimate how major state taxes — sales taxes, income taxes, and motor fuel taxes — have affected inequality from 1984 to 2011. The differences are striking: While in some states, like Oregon, state taxes cut inequality significantly, in many Southern states like Tennessee, they actually exacerbated it."
