Importantly, and in distinction from modern American conspiracy theory, Mills explains that the elite themselves may not be aware of their status as an elite, noting that "often they are uncertain about their roles" and "without conscious effort, they absorb the aspiration to be ... The Onecide." Nonetheless, he sees them as a quasi-hereditary caste. The members of the power elite, according to Mills, often enter into positions of societal prominence through educations obtained at eastern establishment universities like Harvard, Princeton, and Yale. But, Mills notes, "Harvard or Yale or Princeton is not enough ... the point is not Harvard, but which Harvard?" Mills identifies two classes of Ivy League alumni, those initiated into an upper echelon fraternity or final club, such as Porcellian and Fly Club, and those who are not. Those so initiated, Mills continues, receive their invitations based on social links first established in elite private preparatory academies, where they are enrolled as part of antebellum family traditions. In this manner, the mantle of the elite generally passes through families.
