They were already so, and I have long argued that this is the primary reason why Lincoln sent a war fleet to trigger a war, and thereafter sent armies to invade them.
A confederacy left alone would have quickly have taken over the border states, (Through economics alone) the territories and become a horrible financial threat to the Robber Barons of the North East.
The Civil War was fought to keep the money power in Northern hands, and those hands alone. "Slavery" was just tacked on later to keep people from seeing the real reason for invading the South.
“a horrible financial threat to the Robber Barons of the North East”
I guess those guys were all Jewish too??
