“Categorically Unequal: The American Stratification System” by Douglas S. Massey

 From Amazon…“The United States holds the dubious distinction of having the most unequal income distribution of any advanced industrialized nation. While other developed countries face similar challenges from globalization and technological change, none rivals America’s singularly poor record for equitably distributing the benefits and burdens of recent economic shifts. 

“In Categorically Unequal, Douglas Massey weaves together history, political economy, and even neuropsychology to provide a comprehensive explanation of how America’s culture and political system perpetuates inequalities between different segments of the population.
