The troubles associated with declining citizen working population lies not with pseudo-extinction. There are two big concerns with countries facing this. One is the fact that there is going to be greater immigrant representation, and immigrants will have/need to have a separate voice. If a society is not well-equipped to handle this, it can face problems from that. The other is that typically, the ratio of dependents to workers tend to get further skewed, with more dependents being supported by a single worker. This makes for hardship for the population, if not adequately addressed.
