Why have we made so little progress?

Sometimes it's reassuring, but often times very sad, that the strains of history repeat themselves in ways that show how little we've learned. From 1915 to 1970, the internal exodus of almost six million African Americans from the South changed the face of America. For her award winning book The Warmth of Other Suns: The Epic Story of America's Great Migration, Isabel Wilkerson interviewed more than a thousand people to tell the dramatic story of how this American journey unfolded. What happens to one the three central characters in 1945 Florida, shockingly parallels the recent killing of Trayvon Martin.
