In an earlier post we reviewed research by epidemiologists Richard Wilkinson and Kate Pickett showing that income inequality contributes to a whole host of negative outcomes, including higher rates of mental illness, drug use, obesity, infant death, imprisonment, and interpersonal trust.

She summarizes these findings in this quick nine-minute talk at a Green Party conference:

See Dr. Pickett making similar arguments as to why raising the average national income in developed countries doesn’t make people happier or enable them to live longer, why unequal societies are more violent, and how status inequality increases stress.
