I actually think the South would have fewer hick towns if it had won the Civil War, because it was the war and its aftermath that destroyed the South's wealth. It was a very rich place before the war, with all that implies for education and civilization. It's been the poorest region of the nation ever since.
Thanks for ending slavery, though. Actually, two of my ancestors were in Sherman's army, too.
