A good and thought provoking read. This is obviously navel-gazing, but looking at this from an individual or family perspective, I'm wondering about how you could prosper in a depopulating, aging, and warming world. Traditional investments like real estate and property may not be solid bets if there are suddenly a lot of it to go around due to there being less of us around. Then again, city growth seems stable. Anoth…
Stock market? As you write - what will happen when the next generation of consumers and workers won't be born? On the other hand it is clear that market is anything but rational, and maybe it doesn't really need people in the same way internet doesn't need real people. Maybe the future is bots trading with each other, pumping up the bubble.
Bonds? The same problem, lack of next generations.
Real estate? Land? Maybe if you already have something in very good location, though even then I am a bit skeptical.
Then one needs to remember that money is just a number. It doesn't matter how much digits you have, but what can you get with them - real resources and services. So maybe the question is wrong from the very beginning.
I sometimes believe that ironically the best insurance in childless world are your own children. Unless, of course, we will face a scenario where old people, constituting majority of the population, will squeeze those few remaining young hard to get their pensions and healthcare. Yes, the same people that today preach about how it is good to not have children etc. will be first to put a boot on them in the future. For this reason I expect growing tensions between those people with children and childless ones.
This is why I constantly find most such discussions on demography pointless, as participants rarely understand how everything in our society depends on the assumption that no longer holds - that there will be more people, and that young will be more numerous than old.
In the end probably best things to safeguard you in the upcoming crisis will be the same as always - local community, family (including children), friends and your own skills. People living in more agrarian societies, or just in the countryside, generally have better situation in that regard.
