Wealth Gap: A Guide to what it is, why it matters.

Q. Hasn't there always been a wide gulf between the richest people and the poorest?
A. Yes. What's new is the widening gap between the wealthiest and everyone else. Three decades ago, Americans' income tended to grow at roughly similar rates, no matter how much you made. But since roughly 1980, income has grown most for the top earners. For the poorest 20 percent of families, it's dropped. Incomes for the highest-earning 1 percent of Americans soared 31 percent from 2009 through 2012, after adjusting for inflation, according to data compiled by Emmanuel Saez, an economist at University of California, Berkeley. For the rest of us, it inched up an average of 0.4 percent. In 17 of 22 developed countries, income disparity widened in the past two decades, according to the Organization for Economic Cooperation and Development.

Q. So why has income inequality worsened?
A. There's no simple answer. Globalization has created "superstars" and concentrated pay among corporate executives, Wall Street traders, popular entertainers and other financial elite. At the same time, factory workers now compete with 3 billion people in China, India, eastern Europe and elsewhere who weren't working for multinational corporations 20 years ago. Many now make products for Apple, Intel, General Motors and others at low wages. This has depressed middle-class pay. And pay has risen much faster for college graduates than for high-school graduates. These trends have contributed to a "hollowed out" labor market, with more jobs at the higher and lower ends of the pay scale and fewer in the middle.
Oh, by the way . . . . PLLLEEEEAASSSE don't read the comments section. It's too early and you'll just get angry at the ridiculous amount of red-baiting, dog-whistling, false dilemma "arguments", Horatio Alger paens and general stupidity that's expected of the Cheeto munching basement dwellers that comprise Yahoo's audience.
