When you say "holistic" admissions, I'm not sure whether you mean holistic in the sense that colleges use it (i.e. taking evidence of talent outside of grades and test scores into account) or as a reference to programs which take race or class into account. Either way, you present standardized tests as the more meritocratic approach, which is silly. A perfect SAT score means a student is great at basic math, reading, and writing in an extremely specific context. That can be an extremely useful foundation, but do you honestly think that indicates this student is the "best?" That someone with lower scores who has published a bestselling book or won an international science prize or started a great humanitarian effort is on a lower tier in the meritocracy? Of course, all of these things are biased even more heavily towards rich students, but that's why class and background must also be taken into account.
I suspect I may have misunderstood parts of what you were saying, so please do clarify (if you can make it through my little word dump :P).
