Slaves today is a bit much, as I think you know, Bobert. But slaves til the end of the 19th century--and maybe beyond--is not stretching it. Slavery was just too comfortable for the men at the top of the system that they would want to change it. If anything, there might well at some point have been--extremely bloody--slave revolts. Nat Turner writ large--and that was what the slaveowners lived in dread of--and always had wherever the slave population had started to exceed the white.    The example they saw was Haiti.

Slavery was not going to go peaceably. I've seen no evidence--from anybody--that it would.
