Well, we also organize the systems that organize people into hierarchies, and our normative choices are just as "natural." And, to continue this kind of thinking, the mushroom clouds of the next nuclear war will also be nature's means of expression, as was slavery, and also the emancipation of slaves.
Please show me where I said that hierarchy or ranking was bad -- I was trying to say that we can control the shape of our societies, including the forms of inequality, hierarchy, ranking and so on. The comment I was replying to portrayed weakened immune systems from high social inequality as something that was just part of "nature" as matter organizes itself. Well, we are that matter, and we have this amazing ability to make choices. Look at the diversity of social orders even just in Hellenic Greece, even simply comparing Sparta, Athens, and a kingdom or tyranny.
Also, if you're implying that this human world is a functioning meritocracy, then I just can't agree. For example, just try to convincingly guess where Donald Trump would be if he'd been born into poverty.
