Actually we don’t know but that these are the people who would have made more money even if they had not gone to college. There are a couple of things that indicate rather strongly that this is so. Colleges get a disproportionate number of two groups of kids: the bright and the rich. The bright might show good earning power without college knowledge. And as for the rich ones … well, money breeds money in several obvious ways. Few sons of rich men are found in low-income brackets whether they go to college or not.
