My argument is if a person doesn't have the time and money for prep courses, etc. they are lazy. I worked 2 jobs for 50+ hours a week to put myself through school and pay rent. If I can do that, anybody can.
And, as far as work experience, life experience, etc. helping to influence admissions decisions - were it only true!! I think it is true in borderline cases, but for the most part schools are numbers driven. No amount of soft factors can make a 159 competetive at a T14. When a candidate is admitted to Harvard or Yale with extremely low numbers, I would hazard a guess that it is because they are the "right minority."
I am totally aware that in the world certain minorities experience things that whites or other minorities may never understand - however, we are all individual human beings and we need to be judged as individual human beings. It may not be the reality of what happens, but that doesn't mean it makes it okay to perpetuate these prejudices.
Because I don't work in admissions, I can't say how much soft factors matter, but I do know that numbers aren't all that's involved. Soft factors can explain/make up for low numbers. And it doesn't just do that for Black students.
Yes, we need to be judged as individual human beings, but in the real world, we aren't. If we were to use the same system in admissions that is used in the real world, there would be serious problems.
