"Inequality kills. Both rich and poor die younger in countries with the greatest inequalities in income. Countries such as the United States with big gaps between rich and poor have higher death rates than those with smaller gaps such as Sweden and Japan. Why? In this provocative book, Richard Wilkinson provides a novel Darwinian approach to the question. This is a penetrating analysis of patterns of health and disease that has implications for social policy. Wilkinson concludes that rather than relying on more police, prisons, social workers, or doctors, we must tackle the corrosive social effects of income differences in our society."--Jacket.
