"Because dependency is another name for power. The relationship between dependent and provider is the relationship between client and patron. Which is the relationship between parent and child. Which also happens to be the relationship between master and slave. There’s a reason Aristotle devotes the first book of the Politics to this sort of kitchen government. Modern Americans have enormous difficulty in grasping hierarchical social structures. We grew up steeped in "applied Christianity" pretty much the way the Hitler Youth grew up steeped in Hitler. The suggesting that slavery could ever be or have been, as Aristotle suggests, natural and healthy, is like suggesting to the Hitler Youth that it might be cool to make some Jewish friends. Their idea of Jews is straight out of Jud Süß. Our idea of slavery is straight out of Uncle Tom’s Cabin. If you want an accurate perspective of the past, a propaganda novel is probably not the best place to start. [...] We think of the master-slave relationship as usually sick and twisted, and invariably adversarial. Parent-child relationships can be all three. But they are not normally so. If history (not to mention evolutionary biology) proves anything, it proves that humans fit into dominance-submission structures almost as easily as they fit into the nuclear family."
