@queenmother - I agree with the general sentiment of your post, and it seems that more and more people are acknowledging what is obvious, and which incidentally is where I began my posts on this thread: schools use a (perhaps soft) quota or “bucket” system in order to assemble their classes. Within each bucket the kids compete largely against one another, and it is an open question to my mind whether even that competition would be seen as “fair” if the particulars were known.
I disagree, however, with a few specifics in your post, specifically that the number of buckets is “never ending.” My contention is that the parameters of these buckets are dictated by current elite thinking. Not so dissimilar to how the buckets were arranged 50 years ago; although the buckets themselves have changed, that they reflect the preferences of a small group of elites has not.
The takeaway for potential applicants, if they believe my reasoning, is that applications should be tailored to those elite preferences, where possible. For instance, I do seem to recall at least a few applications that asked whether the student identified as LGBTQ, although I could be wrong. In any event, if the student happens to be, or believes him- or herself to be, LGBTQ, highlight that in an essay. At least I could imagine myself offering that advice. Conversely, if the student is vehemently pro- traditional marriage, I would advise to hide that. Similarly, if a student is Muslim, highlight that. A born again Christian, well, not so much. The buckets are not unending, and it’s pretty obvious what helps or hurts. Just turn on MSNBC or, like me, spend a day reading opinion pieces in the Exonian!
