And before you get all offended let me point out that the abolitionists wanted slaves to count as NOT HUMAN. 0%.
If any of us could go back to 1810 and see the conditions under which our American ancestors lived, we would be shocked at the discomfort, poverty and squalor. The modern middle class is purely an American creation, and is fading rapidly. I visit historical plantations and listen to the tourists go tsp-tsk over the slave cabins. It is very likely that their own ancestors never knew such comfort!
