best line in the film...
"He didn't realize that being poor was what was killing him."
In other words all the racism from the poor whites was simply misdirected anger at a group of people (blacks) who had nothing to do with their situation. The wealthy Southern white establishment had always used that to maintain the social order of the South. Its no wonder in the last weeks and months of the Civil War, disillusioned confederate soldiers were talking about the conflict as a "rich man's war but a poor man's fight", for it was in those last days they finally realized they were being used as pawns by cotton kings and other wealthy elites who didn't want their ante-bellum plantation "eden" to disappear forever.
Great film...
