Migration and the global middle class

The final panel considered whether it was productive to approach migration from the perspective of a global middle class, a concept first advanced by economists in the early 2000s (Milanovic & Yitzhaki, 2002). While they defined it in quantitative terms, does such a class carry distinctive qualitative traits or a shared identity or set of values that apply across borders? Do we see evidence for the theory that 'postmaterial' values are becoming global as middle-class lifestyle spread (Inglehart, 2018), and how does this relate to migration? Can it be linked to particular temporal (present-oriented) and spatial (downscaling) aspirations? How does migration both reflect and constitute social stratification? Does the migrant middle class develop new class sensitivities that could be critical of sending-country class structures or are class identities transplanted seamlessly? If there is a global middle class, does it reconfigure global racial hierarchies?
