Irony in the Civil War

What is ironic about slaves fighting for the South in the civil war?

JI: The elites were tricking people into thinking skin color is more important than economic freedom.

EK: People who were fighting in the Civil War from the South were often formerly poor, indentured servants. The elites told them that skin color was more important than economics. By keeping slavery, the blacks actually had the white former indentured servants' jobs because they were free labor. But the white former indentured servants were told that if the blacks were freed, that "black people will take your jobs."

KL: An elite group of people convinced indentured Eurpoeans that skin color matters so they would feel superior to blacks. The elites told the poor white people that if the colored people were free they would take their jobs. It's ironic because the black people had the white people's jobs!
