what is Occupy Wall Street (OWS) ?
it is a protest movement which began September 17, 2011 in Zuccotti Park, located in New York City's Wall Street financial district, initiated by the Canadian activist group Adbusters.
The protests are against social and economic inequality, high unemployment, greed, as well as corruption, and the undue influence of corporations—particularly from the financial services sector—on government.
The protesters' slogan We are the 99% refers to the growing income and wealth inequality in the U.S. between the wealthiest 1% and the rest of the population. The protests in New York City have sparked similar Occupy protests and movements around the world.
