Income inequality is a hot topic for 2014. The liberal Center for American Progress recently launched a new center devoted to the subject, and President Obama has been making it a centerpiece of his speeches.

Wriston Fellow at the Manhattan Institute, and Donald Schneider of Heritage’s Center for Policy Innovation reveals that “The evidence across local job markets in the United States throws severe doubt on the idea that income inequality harms opportunity.”
