"This is actually the origin of the ruling class and the ruled class. In the beginning, when humanity was still in its primitive stage, there were always individuals who were stronger, better at observing, and better at summarizing. They stood out from the masses and gradually became clan leaders. This is all common sense. As human civilization developed, slaves and slave owners, feudal lords and serfs, emperors and the common people emerged. Even when humanity entered the 21st century, this setup essentially remained unchanged. The only difference was that more layers were added to the hierarchy, making the class conflicts less acute. But overall, the so-called rulers and the ruled have always been about self-preservation in response to nature, and this has never changed."
