I found this article to be very interesting and very thought provoking. Admissions is certainly interesting and by no means is it fair.
Article from Vox — from a former Dean of Admission
This article really made me think about Early Decision. Does it help with admission — absolutely. Does it help a coach with roster management — absolutely. Does it help the institution — absolutely. Does it help disadvantaged students — nope.
Also very telling that the first three issues pointed out all deal with wealth.
