Sad to see this downvoted, because it's a good point. Not so long ago, all the talk was about preventing overpopulation and reducing birth rates. China had their one-child policy, which was very heavy handed and lead to a ton of problems, including gender-based abortion (or even child murder), but nobody disagreed that a reduction of population growth was necessary. It's just that everybody in western countries felt that education and access to birth control were the better option.
Now that some countries actually have shrinking populations, everybody switched from panicking about overpopulation to panicking about having not enough working population to support too many elderly people. Immigration is the popular way out, but somehow I'd expect this shouldn't have been such a big problem in the first place. A couple of decades ago, women barely worked (paid, that is; they were probably overrepresented in unpaid elderly care).
I don't think a shrinking population should be this big a problem for a country. Sure, it probably requires some economic choices, just like everything does. But especially for densely populated countries dealing with housing shortages, a lower birth rate shouldn't have to be a bad thing.
