Actually, slavery is still practiced in the USA today. Blacks, and legions of refusal to work whites, have endured themselves to the Marxists Dimocrats for everything they need or want. What is the difference? They are still slaves to the Marxists. They just don't see it that way because they get free stuff.
That’s not slavery. They are free to get work if they want it. They just find it easier to take free government money and live on that.
