Methodological nationalism as a critique of container-based and nation-state-focused theory and empirical research is currently strongly anchored within migration studies, where it was initially developed. While this has led to extensive literature and critical engagement with methodological nationalism, and ways to circumvent the national trap in many (sub-)disciplines, it has not much penetrated theories of social stratification. This conceptual paper will address this gap by discussing the social positioning of high-skilled migrants in contemporary stratified societies. This exemplary discussion will bring together a critical perspective of methodological nationalism on class and milieu theory. It will also confront the critique of methodological nationalism with the question of the origin of social power and dominance, which are the foundation of stratification theories. This article will specifically draw on Pierre Bourdieu's concept of social space and its derivative. Emphasis will also be given to Michael Vester's development of social milieu to highlight blind spots according to the critique of methodological nationalism. This paper shows that these theories have not grasped high-skilled migration thoroughly. It also outlines that migrant theories and their critique of methodological nationalism inadequately address the source of symbolic hierarchy and the formation of social stratification. Thus, both theoretical strands would benefit from a deeper conversation with each other.
