Slavery was a great capitalist concept. I wonder why they ever did away with it? Slavery was run by wealthy people. It should have been respected. Slavery is rooted in mindsets that totally conflict with the concept of a free market and individual rights.
State-sponsored slavery, apartheid....they're all forms of ethnic and racial socialism.
The greatest power in a free or even semi-free market is the middle class, a concept that goes all the way back to Aristotle.
