Oh so you mean that admitting people into situations they academically wouldn't otherwise qualify for, because of their extra-academic factors, would result in them being unable to keep up? Who would have ever thought that?
I just find stuff like this hilarious. It's clear that over history, people do what is necessary to achieve a goal they really set their mind on. If we make that goal easier to achieve, people work less hard and it basically negatively reinforces their behavior. Soon, people who desire the same goal will work even less hard and except more help making their goal easier to achieve and thus you create a system of failure. If we actually make people work for what they get, they realize " hey if I work my @ss off, I can get this! And so they do, and take the spot of someone who isn't willing to work as hard and thus we've positively reinforced effort and determination. But hey, we should just give everyone everything for free. YAY
