Seems he gently skipped over the fact that getting a job is supposed to be easier if you have college. Thus he would have to take into consideration all those people who can't get a job without it, or who would have to accept sub-par employment with low pay. Suppose also that you will only do well in College, and thus be elligible for those well-paying jobs afterwards, if you already did very good at primary school. If we suppose that only pupils with high grades from primary school can "make it" with College, then that would also be another point that I think the article explored only weakly.
