The world-historical approach certainly offers a solid methodological and empirical basis for explaining the enduring prominence of class and status as the primary dimensions for the analysis of social inequality in terms of an overgeneralisation from the Western European experience. Methodologically, Korzeniewicz and Moran are thus quite close to recent transnational migration research, which advocates a mix of international comparison of individual nation-states, world-systems analysis, and transnational perspective in order to adequately account for twentieth-century world inequalities, and accordingly differentiates between the units of analysis, the units of reference and the units of observation of each. Thus, the reproduction of colonial and imperial racial hierarchies in countries of immigration today leads Mignolo to declare global citizenship a myth. The persistent divorce of global approaches to gender inequality from the rest of global inequality research is in this context particularly striking, as it reproduces the division of labour between feminist theory and social structural analysis characteristic of twentieth-century sociology.
