>It seems unlikely to me that any species capable of crossing the interstellar void has much use for slaves. Based on what? There's literally no reason for there to be slaves in the human race in 2021, but there are. Why do you think that suddenly changes just because you can get to another planet? Hell, aliens may enslave other intelligent beings for the sheer enjoyment of it. Assuming their actions in any way reflect humans and our societal morality is a pretty arrogant and dangerous way to think IMO.
