Bagchi analyzes this capitalist world not in terms of how much growth it made possible but how much human development it made possible, and in this regard he finds it very wanting. One of his principal services to readers is his pulling together of the demographic literature on life expectancy, the public health literature on disease prevention and cure, data on nutrition, income levels, and the various forms of labor coercion to give us a nuanced picture of human development over time and throughout the world, one that is differentiated by geography, age cohorts, and gender.〔(The Human Costs of Economic Growth )〕
