Hierarchies are inevitable. They are a consequence of living, of existence.
I breathe, microbes die in my saliva. I walk, things that I don't even see get killed under my feet. One spouse washing the dishes, the other one watches TV. Some people work harder their jobs, others slack off. The sun is a star, Pluto is not.
Hierarchies are inevitable. You would not exist if it wasn't for hierarchies.
