I am very surprised nobody has picked up this line for discussion: " Success in escaping [..] was also influenced by the educational level of the parents, a higher rate of success being associated with fewer years of education attained by mother and father combined. "

There's no attempt at explanation for this in the article itself..

Would it be safe to deduce that the more educated "you" are, the more passive (or "inactive") you are in the face of danger?
