Interesting interview with Loni Guinier in which she discusses her research into class and race, and how the two are often mistaken for each other, as well as the prediction value of measures of "merit" used for admission to colleges and laws schools.
One of her observations is that grades and test scores are not very good predictors of school performance or life performance (as measured by a definition of good alumni - my term, not hers), but class is. Blue collar admittees make better alumni.
Also, discusses briefly the Hopwood case, and points out that Hopwood was as much a victim of UT's admission policies discriminating against the poor (or at least those unable to attend elite universities, for whatever reason - which could be unrelated to wealth) as she was UT's preferential admission of other races.
