I think there's a lot of collective trauma (i.e. abuse) that is transferred from group of elder to the next group.
the idea is how this is similar to parent-child abuse "chains"... to summ up, in the psychologist's phrase: "either repeat your trauma or fix it" but with the added complexity that this is happening to entire groups of people traumatizing and insisting on repeating (passing on) trauma to the next younger group "because that's what they do" or some other weak excuse. the kind of excuse that psychology (taken as one whole field) solved for the individual personality.
however, the complexity pulls the problem beyond the field of psychology, and into something which also involves sociology and possibly anthropology, to say the least
