[Harmless Teddy Bear]

Apparently few people on this thread read Sci-Fi. A lot of Sci-Fi have a slavery thread. And why not. It has only been recently that humans in general have regarded all slavery as bad rather then just bad if it happens to you or people who are like you.

In all likelihood slavery will make a comeback as we spread out into the stars or remain on earth. People like to have people they can order around who have no option but to obey. It is a sad and unpleasant character flaw in some humans.

Yes. I think Edgar Rice Burroughs wrote books in that vein (Mars). I only read Tarzan and some Pellucidar.
