Therein lies the eternal problem - “just”. Who decides what is just? How is it qualified?
Some would say that assistance should be needs based. The neediest students receive the tuition. But what if you have one allotment left and two students competing for it. One is more needy than the other, but the other appears to be more qualified than the other. Does the second person get it or does the first, needier person get it? Then, you have to trow in minority status. The institution in which I work is actively recruiting more minority students. Some might be less qualified than a more needy non-minority applicant. Who should receive the assistance?
What is the just thing to do? Who decides on what the just thing to do is? It is a really complicated issue. That is probably why things rarely move forward or why something is passed only to be repealed later as the winds shift.
As a non-minority who paid for his own education, I largely do agree with you, though. I am just pointing out the difficulties institutions and legislators face when making these decisions.
