Children of divorce, do you agree with this quote?

There are some scientific theories behind this. For most of human existence, life was short and plagued with death, starvation, disease and violence. The loss of a parent signaled to a child that they were living in a high danger area, so they needed a different set of skills to survive. The best strategy was to have a lot of kids young, adopt more of a "every man for himself" attitude. And we generally see this reflected in single parent families. The kids are more restless, more wild, have a higher incidence of teen pregnancy. It's just one theory, but it does explain why it has such a large impact.
