What is a pyramid and hierarchy of power? what role does the need for power play in it?

In almost any society, there is a hierarchical structure in one form or another. Even if we talk about indigenous tribes in Indonesia, then they have their own structure. It may be less pronounced than in the Western world, but they also have their own leader and other people who obey him. There are people more valuable and less valuable. As a result, some are higher in their status, while others are lower.
