On this week's 42nd anniversary of King's assassination, Bill Moyers sits down with attorneys Bryan Stevenson and Michelle Alexander to discuss how far we've really come as a country, how poor and working class Americans have been falling behind and what America must do to fulfill Dr. King's vision. And a Bill Moyers essay on inequality in America.
