I am asking a very vague question here but I've been pondering about it lately. Why is our society like this? As in, why does our society has criminals, why do we have social hierarchy, why do we try to gain power and fame etc. (and lots of other things) I cannot help but think about all this from a scientific point of view. Does having a social ladder beneficial in an evolutionary point of view? Has power and fame anything to do with it? I am not sure what I am asking here, but basically what I want to know is: Instead of a simple society where everyone shares resources, live and reproduce, why are we living in such a complicated society? Hope I make sense.
