I'm looking for specific and non obvious answers. Give me something visceral, rid the world of a figure or nation you hate. Preserve a culture you adore. It doesn't have to make sense either, you are basically god here.
What I mean is don't just say you'd get rid of imperialism or colonialism bc no shit
Personally I would make it so that the Americas are never discovered by the old world and every "would be" conquistador (especially cortez and pizarro) explodes.
I think I hold the same position as Graeber, I was just keeping it simple.
For example that's partially why I said "all" tribes. I agree that it didn't happen linearly, and agriculture wasn't adopted by all groups at the same time. As Marx pointed out late in his life, many tribes had instead adopted a proto-communism that didn't derive from a local implosion of the capitalist order. However the exploitative form of material relations has nonetheless become dominant over the course of millennia. It is obsessed with subjugation and highly normalized. Therefore I think preventing its instances of origination would have led to the development of very different civilizations.
