"The invention of the 'consumer' identity has been an important part of a long process of eroding workers' power, and it's one reason working people now have so little power against business. According to the social historian Stuart Ewen, in the early years of mass production, the late nineteenth and early twentieth centuries, modernizing capitalism sought to turn people who thought of themselves primarily as 'workers' into 'consumers.' Business elites wanted people to dream not of satisfying work and egalitarian societies--as many did at that time--but of the beautiful things they could buy with their paychecks."
