Who joins Greek organizations, Socialites or Wannabes?

The privatization of higher education is producing a divergence in the student body of colleges. With increasing prices, students reigning from upper class or more well-off families find themselves much better prepared for both college life, and life after college than their average, middle class peers. In the work of Elizabeth Armstrong and Laura Hamilton, Paying for The Party goes on to describe the means by which this inequality develops. The elitist "socialites" tend to not only have a better time in college than their "wannabe" peers, but they are also better prepared for the real world after college. With more money at their disposal college is much less of a struggle for the socialites. Furthermore, their sociability pays dividends in the long run compared to the social networks the wannabes build in college. 

There seems to be a parallel between these socioeconomic factors and Greek letter organizations. The Fraternity or Sorority is based around an idea of mutual development. Being active in a Greek organization builds leadership skills, interpersonal networks, and allows social outlets to flourish. These are much the same outlets that allow the socialites to flourish in college. My question is; are greek organizations a means to which the average student can tanscend the inquality developed by privatized education, or do they further perpetuate this cycle by facilitating the socialite class.

As portrayed in Paying for The Party, these "pathways" develop because of economic inequality. More economic mobility equates more social mobility which pays dividends in the long run. In joining a Greek organization there is a large monetary commitment. Moreover, to be given the opportunity to join a Fraternity or Sorority one must be selected as a fitting candidate, and then, only after weeks of proving your worth (i.e. pledging) are you initiated into the organization. The selectivity of this process appears to play heavily into the inequality developed by privatized colleges. The same students who fall into the socialite class, with more money and more social connections are seemingly more prepared to join a Greek letter society. Through offering social connections which can lead to jobs and internships and social outlets such as parties and formals, members of Greek letter societies share many of the perks the socialite class of student experience. However, through selectivity and monetary contributions, the socialite class is also the most prepared to join a fraternity or sorority. Because of this, Greek letter societies and the privatization of school are intrinsically tied. Fraternities and Sororities perpetuate the same type of inequality that developed through the privatization of school. Although not their goal, the opportunities that Greek societies offer are, for the most part, only accessible to the socialites who are exposed to these opportunities anyway.
