Maybe it's dull and uninteresting but unless you keep it in mind at every layer of abstraction, you run the risk of drawing incorrect conclusions. People tend to recognize this fundamental lack of control in only the most obvious cases like familial wealth, race, nationality, iq etc.. but completely ignore it in the more subtle and important distinctions between people like early childhood experiences, stress in the household, metabolism, serotonin levels, emotional tendencies and intellectual influences. The sheer complexity involved in all of these factors causes them to be treated differently and unfairly reduced to "idk some people just get ahead in life because they work harder."
