How economic inequality harms societies

[pegkerr]

"We feel instinctively that societies with huge income gaps are somehow going wrong. Richard Wilkinson charts the hard data on economic inequality, and shows what gets worse when rich and poor are too far apart: real effects on health, lifespan, even such basic values as trust."

...

"I think the take home message..is that we can improve the real quality in human life by reducing the differences in income between us."

GNP per Capita isn't predictive. But income inequality is. Very persuasive.
