There is just one, single reason for the decline of births in so-called developed or developing countries - women emancipation. Anything else is simply a cope from people that are unable to acknowledge the fact that everything has a price.
You are presuming intentions that are absent from my comment. And it doesn't state any "argument".
I am not saying there that it is wrong to give women such freedom, nor that it is right. Maybe there is an alternative cultural setting where women emancipation doesn't bear such consequences. Maybe not. Maybe it is an unavoidable result of our societal progress. Or maybe a flourishing of the society cannot, and shouldn't, be measured in births-to-deaths ratio.
These things I consider unknown. But the cause of the current state of affairs is as stated.
