Perhaps my use of "society" overemphasized the culture aspect that you pick up on. "perserving culture" is of a secondary importance to me, what's more important is the people themselves. As you say, the memes will be able to fend for themselves and survive even if the people in the society do not. People are not merely the transmission vectors of DNA and memes.

Global population may be growing (for now) but the rate at which its growing is decreasing [0].
Further, (and I wish I had a source at hand) the problem with relying on immigration to sustain population levels in a country is that many countries do too good of a job at assimilation. The fertility rate of immigrants rapidly converges to the local level over the course of 2-3 generations.
> You are worried about a decline in children in a set of countries. I’m worried a decline in children, immigrants, population, in every country in the world simultaneously.
I don't think that's true. You and I are worried about the same thing. I look at Japan and Korean as habringer of what's to come for the rest of the countries in the world (and thus the world as a whole), i.e. an aging population without enough children to maintain any semblence of the current way of life working, much less to replenish the population.
Honestly I'm trying to play devils advocate here a bit for the sake of dialouge, cheers mate.
I would love to save western cultures and the genetics are part of the culture. They just are. The regional adaptions people's bodies have to their climate and geography and local food sources really does influence their interests and their cultures to a degree. Peoples bodies are different and that makes them do different things, that's one example I can think of genetics influencing culture. If all the whites die off for instance there will probably be less people doing extreme snowboarding while chugging milk.
Yet the concerns I've raised I believe we should at the very least be wary of.
