Why was the south for slavery?

Slavery had become entrenched in the South due to their agricultural economy. The way things were set up, slavery was necessary for the way of life that had developed there. There was no painless way to end the practice even as moral objections arose over it. Most whites believed that they were ordained to be the superior race and that blacks were not fully human but were created to serve as inferiors and could not manage by themselves even if they were freed from slavery.
