If there is an unfairness in obtaining opportunity, either lack of education opportunity or whatever, that seems like the right thing to address. Not at the end of the process and then trying to tilt things.
That reminds me of what happens when we see a house on fire: We let it burn to the ground (don't want to upset the status quo of the house on fire), then say we'll make a few small tweaks to the building codes to prevent any house fires in the future.
A major problem should be tackled in all of the areas where there is injustice. The beginning, the end and the middle.
That's not what I'm saying at all. I'm saying (in my opinion), there are other areas more worthy of investment that for whatever reason the populous aren't behind. How about we provide easier and cheaper access to education? More after school programs, child care, social safety nets etc so that disadvantaged groups don't stay disadvantaged.
