Let me start with the political impacts. In the developed countries like Japan and Singapore, there would be more elderly due to the effects of low birth and death rates. Politicians would have to change their campaign strategies to attract the votes of the elderly more than the rest of the population as the elderly form the bulk of the population. This would mean that there would be more retirement homes and elderly friendly features being set up in society all in the hopes of attracting the elderly votes. Essentially, there would be a shift in how politics used to address the needs of the working population to now addressing the needs of the elderly.

Moving on, the socio-economic impacts of these changes would mostly concern the working class in developed countries. They would have to be burdened with higher taxes as the dependency ratio lessens in the wake of a greying population. This higher taxes is needed to build all the retirement homes and elderly friendly facilities needed. Of course, it is unfair to the working class whose earnings are mostly taxed from them. There could even be protests if the taxes reach excessive levels which could lead to social unstability.
