Slavery By Another Name is the story of slaves after the civil war who "journeyed into freedom after the Emancipation Proclamation and then back into the shadow of involuntary servitude." And reveals among other things modern companies who benefited most from "neo-slavery."
I am reading a book with a similar theme right now based a violent criminal in the New York State Penetentiary that a journalist traces his roots back to slavery. It is an exhaustive account of this man's family, Willie Bosket and the treatment of America to his family from the Revolutionary war to modern times. An astounding achievement. All God's Children.
Regardless, there are still books to be read that explain the violence against African-Americans in this country and this is another one. Watch Bill Moyers interview the author. Great work by Mr. Moyers as usual.
