This study is to empirically test the relative importance between class and generation in political orientations, social attitudes and cultural values. Recent social changes occurred in Korea, including the 1997 economic crisis and subsequent neoliberal reform, consolidation of political democracy and ideological freedom, and drastic expansion of information technologies into everyday life, all seem to have contributed to make the generation gap wider and class issues obsolete. Regression analyses of the data drawn from a national sample survey indeed reveal that class is no more a major determinant of virtually all aspects of our lives. Instead, generation turns out to be a more important variable in accounting for political orientations and behavior, attitudes toward work, gender role and marriage, and cultural tastes in Korea, while class is still a major factor for some personal and social issues. The prominence of the generation variable in these analyses seems to pose a serious challenge to the traditional class analysis.
