Maybe not. The German population is aging rapidly, our retirement model (young people pay for old people) is unsustainable and obviously unfeasible by the time I get to retire (in about 35 years), because there are too few young people to pay for the many old people. Right now about 30% of the German population is over 60 years old. I do not have the impression that the government is doing anything to improve the birth rates. If anything it's getting harder for many people to have children. So far the only time a low birth rate is being brought up politically it's to justify immigration, which might be a temporary solution, but whether it's good or not or how it should be done is a different discussion.
