This chapter examines the vectors, spheres, and mechanisms involved in the production and reproduction of inequalities. While vectors refer to the multiple components that shape individuals’ and groups’ positions within the social structure, spheres denote the different social arenas in which inequalities are interpreted, experienced, reproduced, and contested. Among the mechanisms of inequality reproduction, the chapter considers both processes that have been extensively discussed in the literature, such as exploitation and exclusion, and others that have received far less scholarly attention, including externalization and corporeal performance. Drawing on the work of the German sociologist Stephan Lessenich, externalization refers to the capacity of certain social groups and countries to shift the social and ecological costs of their affluent lifestyles onto other groups and regions of the world. Corporeal performance, in turn, builds on poststructuralist conceptions of the body to capture the everyday negotiations through which social positions within hierarchies are enacted but also contested.
