Capitalism arose from European feudalism. Which in turn arose from Christianity. Which in turn became mandated by the Roman Empire right before it totally coincidentally collapsed. The decisions behind this progression were limited to a tiny subset of the local human population, the ruling class which back then was basically seen as a completely different (superior) race compared to the commoners and peasants, to the point they chose to breed with their own relatives instead of polluting their blood with that of the people below them. Therefore, they absolutely did not represent the wishes of most humans at the time and certainly did not represent the "nature" of most humans, just the ones most corrupted by power and exceptionalism in a system they created specifically to keep themselves in power and separate from the masses. They're not human nature, they're the societal cancer that actively rejected and suppressed real human nature.
