I agree with those points but I have not seen evidence for the idea that the availability of social safety nets is not also a significant factor in fertility rate trend, which I took to be the thrust of your original post.

Conversely, I haven't seen evidence that the availability of social safety nets is a significant factor. More data is required, but I still believe my theory is on sound footing based on existing fertility data.

You didn't state a theory; to the extent that you implied a theory similar to the one I described the available data does not support it at all...
