Oh, by the way, it's interesting that the two leading advocates of the "southern way of life," and slavery, John Calhoun and George Fizhugh, were died in the wool socialists. BOth believed in the labor theory of value. Fizhugh wanted to socialize everyone---he flat called socialism slavery, and said slavery (as in the SOuth) was the best way to implement socialism.
Correct me, but iirc Fitzhugh was the slavery-theorist who reasoned that poor whites might make good candidates for enslavement. He was widely read, but not widely credited. People in the South were willing to put up with African slavery, because of their belief in essential racial differences. But white slavery wasn't going anywhere.
