I agree with you: it is a long book, with more problems than can be enumerated and discussed here, but key amongst them is the idea that inequality--the Gini coefficient--matters above all else, and particularly matters more than the absolute improvements in living standards that we (most of us) have experienced in recent centuries. I don't think one's goal should be to enter the ranks of the 'fabulously wealthy'. Anyway, by definition, there will always be a bottom 10% or 20%.
