You are right. Smaller groups/tribes remember in many more countries. Like you said, skin color is maybe not the best example.
Take my situation: I am a German. Our slavery ("Leibeigener") cannot be seen in todays society. It cannot be seen by skin color or any other attribute.
I try to void the statement "Tell me a society which never had no slavery". My argument is: There are societies which had slaves which you cannot reflect in today society. No ones knows, no one is affected.
We have tons of other problems (like the Holocaust and tons of other crimes) we have to work on still today, but slavery among the German society (being a problem today) is no such problem. And I guess, there are many countries where this applies.
I would still consider trafficking of people slavery in everything but name and that is still going on right under our noses all over the world. Hardly anyone cares about that.
