Just look at the "sheepskin effect" (most of benefit of college is in the final degree-granting year) and the representation of Yale, Harvard, and Columbia among Supreme Court Justices (and other elite positions). Furthermore, the model explains some other behavior, such as colleges attempting limit the number of certain minorities that would otherwise be over-represented based on test scores. Specifically, Harvard's quota on Jewish applicants in 1922 and their current lawsuit alleging anti-asian discrimination.
