Kalle Lassen is co-founder of the Adbusters media foundation and Editor and Chief of Adbuster Magazine.  Since the late 1990s, Adbusters and Mr. Lasn have widely promoted Buy Nothing Day, an action that is traditionally observed on Black Friday, the day after Thanksgiving in America, and is now taken hold in as many as 65 countries.  Lasn was also one of the first people to call for an occupation of Wall Street, and despite not claiming ownership of the movement, is widely viewed as one of its central figures.   His new book Meme Wars: The Creative Destruction of Neoclassical Economics will be released November 13th , 2012 on Penguin.  He spoke to me from his home in Vancouver, BC.
