That article by Sowell is excellent and fits exactly with my experience teaching undergraduates poorly prepared for school, blacks and whites. I did not and still do not think it is the job of college professors to teach undergraduate how to READ or do basic math.
It is not. We have screwed ourselves to the wall with all this Affirmative Action BS. I doubt we can recover as the liberals have the schools firmly in hand and they just love Affirmative Action.
