Article has a mild opinionated view of success, which values job satisfaction. High portion of cohort has selected self-contained jobs like those which are readily convertible to a free lancer job(i.e. software developer, carpenter, entreprenuer etc). If you measure the success in social dominance and being closer to apex of hierarchy (becoming a policitian, CEO), I think schoolers would have much better performance on this because school also teaches how to take advantage in social relationships, winning a conflict or making allies.
