‘Countries will also age dramatically, “with as many people turning 80 as there are being born.” ‘
We may soon, be there,by 2030 in California, and in the SW and MW. Most if not many or our syblings, and closest friends are in our 70/80’s or rapidly approaching with zero great grandchildren.
None of our 20 something grand kids/nephews/nieces/children of our friends/relatives are rushing into marriage. They are getting real college degrees or learning/developing real life skills.
The Western women are "empowered". None of the men are interested in marrying them.
You say that like it’s a good thing.
