The Occupy Wall Street protest has entered its fourth week. The grassroots movement started with a few dozen people in New York City and has attracted thousands more over the past 24 days. The protesters address various issues including economic and social inequality, corporate greed and public education.

The protest gained support from dozens of unions on Oct 5. Thousands of protestors in New York have set up an impromptu village in Lower Manhattan's Zuccotti Park. The rallies will continue indefinitely with a major demonstration planned for Oct 15.
