Civil rights and affirmative action didn't come into being out of nothing, they came about because, if nothing was done, things were gonna get real ugly real quick. Things COULD NOT remain unaltered, they were very clearly failing, and the original system could not (and should not have) remained the same just to preserve some ideal that did not suit the reality of modern America.
Now THAT, is an argument I can sink my teeth into, and I don't mean necessarily disagree with. (God I can't spell for sh!t.)
Anyway, I think what you are trying to say there is that:
A. people act in their own self interests
B. the social condition at the time of say, the 1964 Civil Right Act, was intollerable to the populace
So, the people who recognized that "things were gonna get real ugly real quick" got that it was going to get ugly for THEM, real quick. The political structure (republic) of our country allowed for the populace to impact the social condition of its citizenry without significant bloodshed.
And given that, to paraphrase KC, affirmative action became law because the previous system failing, can we assume that affirmative action is becoming illegal now because the current system is failing? If so, then I would say the time for reparation is over.
