Nearby, Micah Chamberlain, 23, a line cook from Columbus, Ohio, held up a sign reading "End the Oligarchy" and said he had hitchhiked to New York. "There are millions of people in this county without jobs," he said. "And 1 percent of the people have 99 percent of the money."

Throughout the afternoon hundreds of demonstrators gathered in parks and plazas in Lower Manhattan. They held teach-ins, engaged in discussion and debate and waved signs with messages like "Democracy Not Corporatization" or "Revoke Corporate Personhood."

Organizers said the rally was meant to be diverse, and not all of the participants were on the left. Followers of the right-wing figure Lyndon LaRouche formed a choir near Bowling Green and sang "The Star Spangled Banner" and "The Battle Hymn of the Republic." Nearby, anarchists carried sleeping bags and tents.
