Ultimately, looking at what has happened over the past few pages, it seems that this is just a debate about childfree and those who believe in having children, wrapped up in religious nuances and economic conditions as reasons.
Regardless, I don't think there is any guarantee that having children or being childfree will make someone rich, because in the end, it all starts with the individual. There is no guarantee that choosing to be childfree will automatically make someone rich because they don't have children to support. Lifestyle, good financial management, and knowing what priorities to focus on for economic development are the factors that can lead to wealth, not whether one is childfree or not. In fact, many people who have children today can become billionaires, while on the other hand, there are also many childfree people who are in the same situation (billionaires) or, conversely, suffer more than those who have children.
