Why did southern states fear the outlawing of slavery?

Southern states feared the outlawing of slavery because they depended on slave labor. The south had slaves doing hard labor for them for free. If the slaves were freed they'd either have to start paying them or find other workers to fill there place and pay them. So the South will loose a lot of money they're earning by taking out a portion of it to pay the workers.

It depends on what you believe, if you’re christian that you would have been told that the first humans were created by god and that we’re all decedent's from adam and eve but scientist say otherwise
