Feudalist societies were not organized by wealth but rather by roles that people were essentially born into. These roles were not achieved but rather understood as basically granted by god. Just as kings had divine rights, people had god-given qualities and understood themselves as having inherent and inherited positions in society, which effectively eliminated all of the social pressure and unusual contortions experienced by subjects under capitalism, even at the level of peasants. So-called fairness as we understand it today was not even a coherent concept at the societal level. Peasants owned nothing but also had far more freedoms and access to resources, which were eventually deemed property as humans entered into capitalism, which forced peasants into capitalist production as workers.
To understand the differences between feudalism and capitalism, you must also understand the conflict between the feudalist aristocracy (god-given) and the capitalist bourgeoise (industrious accumulators of capital). This conict was really the source of the shift to capitalism. The aristocracy could not compete with the capitalists as the capitalists promoted a story of mobility by accumulating capital. Of course, however, only a few can achieve that, and they basically still argue that their abilities are god-given. But the claim about abilities and hard work paying off vs. simple i herited permanent roles results in a much more damaging psychology.
