...cotton was king in the South, the only game in town, ALL of the Southern leadership had made their fortune in cotton and they made slavery the centerpiece of their documents of secession, the causes of secession, and their very Confderate Constitution. THAT is what they wrote.

I'm going with that too. All our lives it was crammed down our throats the war wasn't about slavery, it was about secession.
The south wanted to secede in order to keep their slaves, and their economy intact.
