The Spirit Level nails it. It spells out that the degree of social problem by social problem is correlated to the level of inequality in each country used in the comparisons throughout the book. In the same way that almost everyone accepts the science about the causes of climate change this book provides the basis of a social science and economic consensus. If we want to turn the tide back on poorer health, addictions,stress, crime and get better outcomes in levels of trust and innovation then greater equality is the answer. It adds up , chapter by chapter, to a compelling case.
This book deserves to be required reading for everyone interested in the future political direction of their country. The careful sourcing of data and verification is thorough but in plain english and to the point. It ends with a call to support the equality trust so that soon its clear analysis can be the accepted view. After reading the book I was filled with renewed hope that at least we can pinpoint the problem at source. The authors have been careful to not argue that only one political perspective can provide the solution so long as the starting point of debate is we need to reduce the earning gap between the top and bottom twenty percent in society. Read the book and you will see why greater equality needs to be the starting point of the debate.The Spirit Level: Why More Equal Societies Almost Always Do Better
