I’d say this is probably because of human intelligence. We’re the only species that knowingly (and willingly) go against our better judgment and nature to create absurd practices and societies (like capitalism and complex government systems) to “better civilization” – but it all causes us to go against our fundamental nature as animals, putting us, as @dan3 said, at the top of the food chain.
I’ve often wondered what life could look like if we didn’t have all of these systems around us, constantly trading our time and bodies for pieces of paper that we have given worth, so we can pay for a roof over our head and food to eat. I know modern technology has given us amazing miracles such as modern medicine, renewable energy, and sanitation – but I often wonder what the cost of that is in the long run.
Anyway… exhausted ramblings from me
