In "The Spirit Level," Richard Wilkinson charts data that proves societies that are more equal are healthier, happier societies.

Why you should listen

For decades, Richard Wilkinson has studied the social effects of income inequality and how social forces affect health. In The Spirit Level, a book coauthored with Kate Pickett, he lays out reams of statistical evidence that, among developed countries, societies that are more equal – with a smaller income gap between rich and poor -- are happier and healthier than societies with greater disparities in the distribution of wealth.

While poverty has long been recognized as an indicator for such social ills as crime, obesity, teen pregnancy, Wilkinson and Pickett have demonstrated that societal well-being bears no relation to per capita income. They’ve also found that the symptoms of inequality trouble all levels of society. Across the board, mental health, levels of violence and addiction, even life expectancy are affected by the psycho-social stress caused by income gaps and status anxiety.

In the UK, The Spirit Level won support from politicians both left and right. Wilkinson, who is Professor Emeritus of Social Epidemiology at the University of Nottingham, also cofounded The Equality Trust, a nonprofit that aims to reduce income inequality by educating and engaging the public while supporting political commitment to address the problem.

He says: "While I'd always assumed that an equal society must score better on social cohesion, I never expected to find such clear differences between existing market economies."

Quotes from Richard Wilkinson

The average well-being of our societies is not dependent any longer on national income and economic growth. … But the differences between us and where we are in relation to each other now matter very much.
