In Where Have All the Children Gone?, Pavel Kohou colorfully addresses declining birthrates:
In the third century AD there was a prophet called Mani. He preached a doctrine of conflict between Good and Evil. He saw the material world as the devil’s creation. Marriage and motherhood was a grave sin in his view, since by bearing children people multiply the works of Satan. The Manichean ideal was to move mankind to a superterrestrial realm of Good by way of gradual extinction.In the course of history, Manichaeism was ruthlessly eradicated as an heretical, ungodly doctrine. When looking at demographic statistics, however, one might think that the populations in developed countries have converted en masse to Manichaeism and decided to become extinct. The birth rate in most western countries has fallen bellow replacement level.
Children have shifted from being a valuable investment to being…pets:
To put it straightforwardly, and perhaps a little cynically, in the past children used to be regarded as investments that provided their parents with means of subsistence in old age. In Czech the word “vejminek” (a place in a farmhouse reserved for the farmer’s old parents) is actually derived from a verb meaning “to stipulate”: in the deed of transfer, the old farmer stipulated the conditions on which the farm was to be transferred to his son. Instead of an “intergenerational” policy, there used to be direct dependence of parents on their children. This meant that people had immediate economic motivation to have a sufficiently numerous and well-bred offspring — whereas today’s anonymous system makes all workers pay for the pensions of all retirees in an utterly depersonalized manner.

Today, children no longer represent investments; instead, they have become pets — objects of luxury consumption. However, the pet market segment is very competitive. It is characteristic that the birth rate decline in the 1980s, and especially in the 1990s, was accompanied by soaring numbers of dog-owners in cities. While in the past dog-owners were predominantly retirees, today there are many young couples that have consciously decided to have a dog instead of a baby. These are mainly young professionals who have come to a conclusion (whether right or wrong) that they lack either time or money to have a child. Thus, they invest their emotional surpluses into animals.
