I've been considering the possibility of a "tragedy of the commons" in relation to child-rearing economics within countries with social security systems. It's unclear how many couples take into account the financial impact of having a child on their retirement plans. If they were to do so, the calculations would be rather discouraging. In fact, it could be economically beneficial for a couple to not have children while others continue to do so.

In the past, children served as a safety net for their parents in old age, as parents devoted much of their lives to raising them. However, in a world with a significantly inverted population pyramid, adult children may be responsible for supporting numerous elderly citizens through their taxes. This could potentially leave them unable to provide additional assistance to their own parents. On the other hand, those who chose not to have children could enjoy the benefits of compound interest accrued over 18+ years.

This situation creates a negative feedback loop. As the population declines more rapidly, the population pyramid becomes increasingly inverted, placing greater strain on younger generations to support the elderly. This further exacerbates the economic challenges of having children, as they will be required to work harder and longer hours to sustain the economy.
