This may well be true. But it also may well be not true to the extend that it can explain that decline in US and the differences to similar countries. So far I’ve not seen much data to back up the alleged causality in much of this entire discussion.

sometimes discussions are just to share the opinion and disagreement, not always they contain result of research. I shared my disagreement about specific statement which says: "This decline cannot be explained by demographic, economic, or policy changes" and shared couple of economic and policy issues which might impact the birth rate.

Real reason(s) could be even different, e.g. chemicals used in foods or a plastic? we need a research. But expecting single reason is probably wrong
