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.

In the six-minute video below, Kate Pickett talks about how more equal societies are kinder to each other, give more in foreign aid, are less status-conscious, consume less, and even recycle more.  Based on this, she argues that reducing inequality within societies is a good strategy towards addressing climate change.

How to increase equality? It turns out there are lots of options.

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.
