The collapse of traditional societal guide rails that once encouraged individuals to pursue marriage, children, family, and community engagement has led to a breakdown of values and a lack of willingness to make choices for the good of the whole. This is particularly evident in liberal Western societies that promote ideas of individualism and self-expression over communalism and collective responsibility.
The decision of having or not having children is a personal one, but it can also reflect something about an individual or society as a whole. However, the health of a society or a couple shouldn't be measured by whether they have children or not.
