> However, if the Confederates has succeeded, there’s a good chance they would have ended slavery

[citation needed] do you have some sort of source to back this claim up?

Why would a region willingly give up it’s main source of economic power a la slaves? The south was notorious for avoiding investment into public infrastructure like roads, rail, foundries, etc. Why would they enter into a civil war over slavery if they were “about to give it up” anyways? This take flies counter to everything I’ve read about the confederate south
