Unfortunately their tradition also causes them to work their asses off to such a degree they have even less kids than other developed countries and their restrictive immigration policy prevents this problem from being at least softened a little bit. Whole villages are getting deserted, not because of local industries vanishing like in the US (mostly) but simply because there are no young people anymore causing the necessary infrastructure for kids and teenagers to vanish as well -> nobody moves there -> everything's fucked.

Unfortunately they keep voting for conservative governments as well, so no necessary change ever happens.
