This Site Tells How Much You're Underpaid

Inequality makes a lot of people mad, but it's hard to know where to direct that anger. It's so complicated. Is it because of technology? Outsourcing? The decline of unions? A broken-down educational system? The rise of women? The decline of men? Immigrants? Illuminati? And how do you, as a single human being, fight a complex array of interrelated, systemic abstractions?

To solve this, a handful of economists, programmers and designers labored away for a year and half. The result is an interactive website, launched Monday by the Economic Policy Institute, called Inequality.is. Its goal: to teach people about inequality in America, and to make them so mad they might do something about it.
