"The brightest folks are not always the hardest-working." I sure know it, because I was a bit lazy, but they do tend to go together. Even if they didn't, I'm fine grouping them together. The distinction doesn't matter for my purpose. Crudely, say that success potential is the product of those two. Multiply hours of effort by IQ if you like. Anyway, it doesn't matter for my purpose. "There is more aggregate value in having everyone do a bit better than having an occasional student who's amazing and pampered." That all depends on the trade-off. How much will you hurt the top 10% and how much will you help the lower 50% by the proposed change? If the hurt is great (likely) and the help is minor (likely) then the result is a loss.
