The problems described, although very real, are those of the wealthy in late-industrial or post-industrial societies. For almost all of human existence, the interactions of girls/women and boys/men were closely choreographed primarily for the purpose of reproduction. Secondarily, but of major concern, was maintaining, obtaining and retaining the skills and resources needed for the survival of the family, extended family and group. Things that our biology and cultures supported. Now, however, it would seem that Generation Z and the generation before it have relegated reproduction to a much lower priority and act as if all of the resources required for survival are readily available thus eliminating much of the motivation for individual men and woman to agree on things and form lasting relationships.
