What's this "both sides" and "assumptions"? People who have wealth tend to have much better access to politicians and more control over the economic and social conditions and constraints of a society. Consider for example this: https://www.cambridge.org/core/journals/perspectives-on-politics/article/testing-theories-of-american-politics-elites-interest-groups-and-average-citizens/62327F513959D0A304D4893B382B992B# https://www.cambridge.org/core/journals/perspectives-on-poli... There isn't a need to assume anything. To the extent it's possible to be in a social science, it is a fact that the connected elite (e.g. those who attend Ivy Leagues as a result of their wealth) is "in charge." It's debatable to the extent the data permit, but the "side" asserting the non-elite are "in charge" doesn't have much to offer on that front.
