Was urbanization crucial to southern life after the civil war?

After the civil war many would argue that it was imperative for the south to adopt a more industrialized economy. However I would say this belief tends to be the belief of the north instead of the south. Farming will never be obsolete it is important then and now to have the raw goods. Therefore I would say that urbanization was not crucial in the south after the civil war. The southern economy changed very little after the civil war. The southern economy to a certain extent followed if it ain’t broke why fix it motto. The fact that most southern cities, excluding Atlanta, did not grow simple shows that urbanization was not crucial.
