Scholars, mostly of business but also history, explore the diversity of the middle classes in the Global South, and show how ethical interpretations and behaviors differ in various consumer markets there. The topics include war and famine around the Indian Ocean during the Second World War, religion as apparatus of ethical similarity: a catalyst toward the framework of ethical behaviors in a technical environment, modern business and the doctrine of the mean, and ethics and the unified justice examination of the People's Republic of China. The volume ends with reviews of A. McKay's 2015 The Big Short and the 2017 Humanities, Arts and Social Sciences, edited by J. M. Siracusa.
