"Endless discussions of multiculturalism proceed from the unsubstantiated assumption that numerous distinct “cultures” constitute American society. Only a few historians or observers even consider the possibility that the opposite may be true: that the world and the United States are relentlessly becoming more culturally uniform, not diverse. … No group is able, and few are willing, to stand up to the potent homogenizing forces of advanced industrial society. All Americans, from African Americans to Greek Americans, buy the same goods, look at the same movies and television, pursue the same activities and have—more or less—the same desires for success. … Multiculturalism is not the opposite of assimilation, but its product."
January 1, 1970
