This is part three of our Explaining Socialism Series. In this episode, Prof. Richard Wolff and Brian discuss how socialism has evolved as a concept, doctrine, and guide to action over a longer historical period. Professor Richard Wolff is an author & co-founder of the organization Democracy at Work. You can find his work at rdwolff.com.
