This paper panel session will address the transatlantic circulation of goods, people, lifestyles and tastes that has played a central-role in the structuring of the upper class in both Europe and the United States (especially on the East Coast). The papers will pay particular attention to the different forms of material and symbolic competition shaping the Euro-American relation. It will examine the specific resource that transatlantic ties represent for national elites in a supposedly globalized era. The panel also continues the session on “The sociology of the upper classes in Europe and in the US: comparative perspectives”, which had been organized during the 2011 CES Conference. Beyond the diversity of their methods – archival analysis, in-depth interviews and/or ethnography – these four ongoing researches all look for the best ways toward a qualitative sociology of the one percent as a social group on which the sun never sets.
