BOOKSELF: INEQUALITY IS BAD EVEN FOR THOSE AT THE TOP

THE SPIRIT LEVEL
Why More Equal Societies Almost Always Do Better

Richard Wilkinson and Kate Pickett

John Carey, Sunday Times, UK - This is a book with a big idea, big enough to change political thinking, and bigger than its authors at first intended. The problem they originally set out to solve was why health within a population gets progressively worse further down the social scale; they estimate that together they have clocked up more than 50 person-years gathering information from research teams across the globe. Their eureka moment came when they thought of putting the medical data alongside figures showing the extent of economic inequality within each country. They say modestly that since dependable statistics both on health and on income distribution are internationally available, it was only a matter of time before someone put the two together. All the same, they are the first to have done so.

Their book charts the level of health and social problems - as many as they could find reliable figures for - against the level of income inequality in 20 of the world's richest nations, and in each of the 50 United States. They allocate a brief chapter to each problem, supplying graphs that display the evidence starkly and unarguably. What they find is that, in states and countries where there is a big gap between the incomes of rich and poor, mental illness, drug and alcohol abuse, obesity and teenage pregnancy are more common, the homicide rate is higher, life expectancy is shorter, and children's educational performance and literacy scores are worse. The Scandinavian countries and Japan consistently come at the positive end of this spectrum. They have the smallest differences between higher and lower incomes, and the best record of psycho-social health. The countries with the widest gulf between rich and poor, and the highest incidence of most health and social problems, are Britain, America and Portugal.

Richard Wilkinson, a professor of medical epidemiology at Nottingham University, and Kate Pickett, a lecturer in epidemiology at York University, emphasize that it is not only the poor who suffer from the effects of inequality, but the majority of the population. For example, rates of mental illness are five times higher across the whole population in the most unequal than in the least unequal societies in their survey. One explanation, they suggest, is that inequality increases stress right across society, not just among the least advantaged. . .

Societies where incomes are relatively equal have low levels of stress and high levels of trust, so that people feel secure and see others as co-operative. In unequal societies, by contrast, the rich suffer from fear of the poor, while those lower down the social order experience status anxiety, looking upon those who are more successful with bitterness and upon themselves with shame. . .
