There is nothing to say; Humans are selfish and the ones who form tribes are even more so. Me , you or anyone else with that knowledge can yap all they want about this; nothing will change, humans are and always were two faced. Humanity is the only species in the world that in theory can overcome it's nature and power through it yet every time this is brought up everyone says "maybe in 300 or 400 years", peace? veganism? ending world hunger? stopping wars? gender equality? "Maybe in 300-400 years". Always without any hesitation they scream "FAR FUTURE, NOT NOW."
Hey I don't care if you don't want to end world hunger or achieve world wide peace or if you don't want to abolish meat factories or that you still want to eat meat; I'm just saying that humans are CAPABLE of this; AT ONE POINT they will do this transition and it won't be because we've somehow evolved from today to that point; we could do it starting tomorrow, we just don't want to. Whether something happened like a cultural war or a reevaluation of ethics, Alien cleansing us from evil or us doing it ourselves, at one point we might achieve these things; it won't be because we suddenly gained extra brain matter.
It's always DON'T want to; "But we can't!" screamed some poor individual from the 3rd world country. I agree with you, we can't do it as individuals, I can't do it, you most likely can't but as the whole world? we just don't want to, anything else is kidding ourselves. Society the way we have it is just the most convenient way to fuck others over and pamper yourself at the same time without any consequences. It's quite literally the "get the cake and eat it too". Ego is also a very important reason as to why we don't collaborate with eachother.
The people from the year 1200 even if with good intent could not solve world hunger because of logistics and lack of resources, we are however not the people from the 1200's. We live in 2025, we have enough food and man power to serve everyone and build and assign a system to where people can start then feeding themselves after we put them back on their feet.
Modern Humans WERE always capable of having this train of thought they just were never capable of putting it into practice due to limitations in resources.
Unfortunately it looks like even when we can put it into practice, we just prefer not to because that would help "the enemy". There is no enemy you idiots, only paranoid old fools. The fact that we still wage wars shows how BAD , HOW BAD IT IS , to be forced to live in one country with one history, one ruler and one single thing in mind, revenge against the enemy and being number 1; this is bad because they learn nothing, technology advances, their brains remain the same, meager and archaic.
People need to put themselves in others shoes, it's the most humbling experience and the only way we are getting out of this shithole.
