Kind of like how more experience with nature moved those same societies to not want to destroy it? While it's reasonable to question underlying prejudice and (frankly) very little actual knowledge I do not think that's going to be solved with more experience. We just don't see that reflected in reality. Most of Western society is fossilised, hostile and fundamentally exploitative. Having those attitudes change would involve a complete overhaul of the underlying cultures, which just isn't likely.
