1. When people were poorer than, their retirement plan was their children who will support them when they are old. Nowadays, things had changed. The parents do not need financial support or didn't expect the children to. Thus the people no longer are willing to have children.
2. There was no reliable birth control or safe abortion then. No way to terminate once the act was done.
3. There was no TV or internet. No distractions in other words.
Hence the fastest way to make babies is to destroy TV, internet and make people all dirt poor. Tada! We don't need any more FTs...once the new babies grow up.
