Their complaints range from corruption to lack of affordable housing and joblessness, common grievances the world over. But from South Asia to the heartland of Europe and now even to Wall Street, these protesters share something else: wariness, even contempt, toward traditional politicians and the democratic political process they preside over. They are taking to the streets, in part, because they have little faith in the ballot box. Economics have been one driving force, with growing income inequality, high unemployment and recession-driven cuts in social spending breeding widespread malaise. Alienation runs especially deep in Europe, with boycotts and strikes. The protest movements in democracies are not altogether unlike those that have rocked authoritarian governments this year, toppling longtime leaders in Tunisia, Egypt and Libya. Protesters have created their own political space online that is chilly, sometimes openly hostile, toward traditional institutions of the elite. You're looking at a generation of 20- and 30-year-olds who are used to self-organizing," said Yochai Benkler, a director of the Berkman Center for Internet and Society at Harvard University. "They believe life can be more participatory, more decentralized, less dependent on the traditional models of organization, either in the state or the big company. Those were the dominant ways of doing things in the industrial economy, and they aren't anymore."
