Review excerpt:
Eberstadt and Satel conclude that the ambitious claims of the "inequality hypothesis" school rely all too often upon limited or unrepresentative data sets, hazily expounded causality, econometric fallacies, and results that cannot be replicated. The widespread popularity of the income inequality hypothesis must be explained in terms of non-empirical appeal: namely, the age-old siren song that refashioning society in the name of redistributive justice can improve life prospects for us all, the authors say.
