The authors point out that the life-diminishing results of valuing growth above equality in rich societies can be seen all around us. Inequality causes shorter, unhealthier and unhappier lives; it increases the rate of teenage pregnancy, violence, obesity, imprisonment and addiction; it destroys relationships between individuals born in the same society but into different classes; and its function as a driver of consumption depletes the planet's resources.
Wilkinson, a public health researcher of 30 years' standing, has written numerous books and articles on the physical and mental effects of social differentiation. He and Pickett have compiled information from around 200 different sets of data, using reputable sources such as the United Nations, the World Bank, the World Health Organisation and the US Census, to form a bank of evidence against inequality that is impossible to deny.
They use the information to create a series of scatter-graphs whose patterns look nearly identical, yet which document the prevalence of a vast range of social ills. On almost every index of quality of life, or wellness, or deprivation, there is a gradient showing a strong correlation between a country's level of economic inequality and its social outcomes. Almost always, Japan and the Scandinavian countries are at the favourable "low" end, and almost always, the UK, the US and Portugal are at the unfavourable "high" end, with Canada, Australasia and continental European countries in between.
This has nothing to do with total wealth or even the average per-capita income. America is one of the world's richest nations, with among the highest figures for income per person, but has the lowest longevity of the developed nations, and a level of violence - murder, in particular - that is off the scale. Of all crimes, those involving violence are most closely related to high levels of inequality - within a country, within states and even within cities. For some, mainly young, men with no economic or educational route to achieving the high status and earnings required for full citizenship, the experience of daily life at the bottom of a steep social hierarchy is enraging.

AUSTAN GOOLSBEE: I think the world vests too much power, certainly in the president, probably in Washington in general for its influence on the economy, because most all of the economy has nothing to do with the government.
