Look at this as a 2x2 matrix of possibilities:

A1 - A world with good humans that stays in communism forever wouldn't have our problems. In context of something important to you: there could still be religions called "Judaism" and "Christianity" and "Islam" full of people like you who foster community and philosophical discussion.

A2 - A world with good humans that invents currency and capitalism must have better reasoning and intent behind it than the humans in our world, and thus wouldn't have our problems. Again, the big religions wouldn't have holy crusades.

B1 - if you have a world full of humans with RNG-based hatred in their hearts - so powerful they're willing to sacrifice themselves and their loved ones to also kill their randomly-selected enemies - and those people never invent capitalism, they can still use "Judaism" and "Christianity" and "Islam" as names for religions dedicated to killing each other. They can still refuse to look at any numbers related to crude oil. You could still be born with the same name and DNA you have, to parents with the same names and DNA, with the same birth dates, and all the same death dates. A doctor who tells someone they don't have good enough health insurance might be forced to use harsher words like "I don't personally care enough to help you instead of this other person based on your social status," but if we assume doctors save everyone they can, this wouldn't magically change how many they can save.

B2 - And if you take a world of such hateful violent people and they invent currency and capitalism, that's the world we're in, basically the same as B1 with communism.

The painful thing is being the type of human that could live on side A of the matrix, stuck on side B of the matrix, outnumbered by such humans
