THE SPIRIT LEVEL

In this book advices and real facts areshown to the politics to solve health and social problems for countries that have income inequality is high or equal for citizens. 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.
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.
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. Much research has been done on the stress hormone cortisol, which can be measured in saliva or blood, and it emerges that chronic stress affects the neural system and in turn the immune system. When stressed, we are more prone to depression and anxiety, and more likely to develop a host of bodily ills including heart disease, obesity, drug addiction, liability to infection and rapid ageing.
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.
The different social problems that stem from income inequality often.Babies born to teenage mothers are at greater risk, as they grow up, of educational failure, juvenile crime, and becoming teenage parents themselves. In societies with greater income inequality, more people are sent to prison, and less is spent on education and welfare.
Whereas societies with high income differentials are exceptionally punitive, in Japan imprisonment rates are low and offenders who confess their crimes and express a desire to reform are generally trusted to do so by the judiciary and the public.
