At least as long ago as ancient Greek and Roman times, many sophisticated members of society concluded that investing in children brought no advantage. Rather, children came to be seen as a costly impediment to self-fulfillment and worldly achievement. But, though these attitudes led to the extinction of many individual families, they did not lead to the extinction of society as a whole. Instead, through a process of cultural evolution, a set of values and norms that can roughly be described as patriarchy reemerged.
... Like today's modern, well-fed nations, both ancient Greece and Rome eventually found that their elites had lost interest in the often dreary chores of family life. "In our time all Greece was visited by a dearth of children and a general decay of population," lamented the Greek historian Polybius around 140 B.C., just as Greece was giving in to Roman domination. "This evil grew upon us rapidly, and without attracting attention, by our men becoming perverted to a passion for show and money and the pleasures of an idle life." But, as with civilizations around the globe, patriarchy, for as long as it could be sustained, was the key to maintaining population and, therefore, power.
