You often hear inequality has widened because globalization and technological change have made most people less competitive, while making the best educated more competitive. There's some truth to this. The tasks most people used to do can now be done more cheaply by lower-paid workers abroad or by computer-driven machines. But this common explanation overlooks ... the increasing concentration of political power in a corporate and financial elite that has been able to influence the rules by which the economy runs. As I argue in my new book, Saving Capitalism: For the Many, Not the Few, this transformation has ... resulted in higher corporate profits, higher returns for shareholders and higher pay for top corporate executives and Wall Street bankers - and lower pay and higher prices for most other Americans. [These changes] amount to a giant pre-distribution upward to the rich. The underlying problem ... is that the market itself has become tilted ever more in the direction of moneyed interests that have exerted disproportionate influence over it, while average workers have steadily lost bargaining power. The most important political competition over the next decades will not be between the right and left, or between Republicans and Democrats. It will be between a majority of Americans who have been losing ground, and an economic elite that refuses to recognize or respond to its growing distress.
