" Although for me and most of the people I know, the basis of this book is preaching to the choir, it is certainly good to have our innate feelings supported by clear data and statistics. For people who come from a standpoint of empathy, social justice and social cohesion, it's obvious to us that equality is needed, especially income equality these days. But saying something is the right thing to do morally is one thing; showing it is the right thing to do in a concrete way - showing the good that comes out of more equal societies with hard facts and numbers - is likely to be much more persuasive and effective with regard to those for whom empathy is, shall we say, lacking.
