You could argue that, I wouldn't. While the North was industrialized, the South's economy was agrarian in nature. In addition to tobacco, cotton was a cash crop, and picking it and removing the seeds is even more labor intensive than tobacco. The indentured servants that were used for such tasks had served their time by the late 18th century and were no longer obligated to so. Due to the back breaking nature of the work, they opted not to do it. As the nation began to extend west away from the coastal cities, they began to migrate west into Indian country. Google "Bacon's Rebellion" for an example. The Southern economy relied on slavery, it would have collapsed with out it. It was believed to be a very neccesary evil although it was abhorred by all but the cruelest of people.
