Veblen's work has remained relevant, and not simply for the phrase "conspicuous consumption". His evolutionary approach to the study of economic systems is again gaining traction and his model of recurring conflict between the existing order and new ways can be of value in understanding the new global economy. In this sense some authors have recently compared the Gilded Age, studied by Veblen, with the New Gilded Age and the contemporary processes of refeudalization, arguing for a new global leisure class and distinctive luxury consumption.
