This is what the political scientists Jacob Hacker and Paul Pierson call the "winnertake- all economy." It is not a picture of a healthy society. Such a level of economic inequality, not seen in the United States since the eve of the Great Depression, bespeaks a political economy in which the financial rewards are increasingly concentrated among a tiny elite and whose risks are borne by an increasingly exposed and unprotected middle class. Income inequality in the United States is higher than in any other advanced industrial democracy and by conventional measures comparable to that in countries such as Ghana, Nicaragua, and Turkmenistan. It breeds political polarization, mistrust, and resentment between the haves and the have-nots and tends to distort the workings of a democratic political system in which money increasingly confers political voice and power. - Lieberman, Robert C.
