<human>: I've been hearing a lot about the "Occupy Wall Street" movement. What is it about and who is involved?
<bot>: Occupy Wall Street is an ongoing protest against income inequality, corporate greed, and corruption in the financial industry. It began in New York City on September 17, 2011, when protesters took over Zuccotti Park near Wall Street. Since then, there have been many other protests across the United States and around the world. The movement has spread to cities like Los Angeles, San Francisco, Chicago, Boston, Seattle, and London.
