    .8 birth rate is going to be a huge problem for South Korea in a few years. The rest are just “oh no, capitalism’s infinite growth will be finite after all”

      Lower birthrates are less an issue that people think.

      For any living being self replication can explode incredibly fast, and it’s usually the case when numbers dwindle, due more resources available per person.

      Big birth numbers are more worrying and limited resources lead to fast “too little resources for everyone” situation.

      I remember reading that part of what took Europe our of the dark ages after the black plague was that survivors thrived in an post plague environment. Also remember reading that dutch population growth actually taller because after so many people died survivors got more meat and food in general available to them, so their children grew a lot.

      So in general I’m always more worry about high birthrates than low birthrates.

        This was true back when the economy was vague and vibes based and people kind of just died and it was ok. But now we have pensions, and it’s considered unacceptable for people to starve to death and economies to collapse, so an upside down pyramid starts to get wobbly rather than “self-resolving”.

        The growth (or in this case decline) is exponential. 1.08 is bad, 0.80 is terrifying. 1.08 is roughly half of the fertility needed for a stable population (about 2.1 children per woman). This means that per generation your population shrinks by half its size. 0.8 is another 25% lower. At an exponential rate these differences add up fast. The first one gives you (roughly) one child per 8 great grandparents. The other one needs 18. So over 3 generations the population shrinks by another factor of more than a half.

          But the birthrates are still falling everywhere. Countries that are at 1.08 today will be at 0.8 soon. I think they are just hitting the problem sooner, not that they are facing a different issue.

            Here’s a visualization of the birth rates of Japan, Poland and Germany against those of South Korea:
            https://georank.org/birth-rate/japan/south-korea
            https://georank.org/birth-rate/poland/south-korea
            https://georank.org/birth-rate/germany/south-korea

            Japan and Poland have been stable, maybe slightly declining, since the early 2000s, and Germany has been stable for 50, all below replacement, whereas South Korea is still going down.

            I am no demographic expert, so take this with a grain of salt, but for the moment it doesn’t look like the other countries are going to hit the same problems at the same severity anytime soon whereas South Korea is going to get hit by the full force of their demographic issues within a few short decades.

              I just checked Poland and it’s not what they are reporting:

              Number of births:

              Birthrate:

              Systematically falling for the last 10 years. Yes, it was better before that but experts say it doesn’t look like stopping anytime soon. But I guess we’ll see.

              Those are data from GUS, the official statistics bureau of Poland.

              Far from comprehensive, but a good primer.

              The problem is similar to climate change. The effects of today will ripple several decades into the future, and people everywhere are more short-sighted than they would like to think, you and me included. Our brains are built for hunter gatherer lifestyles, sensing urgency in actions that will come back to us in 40-50 years just isn’t how we are programmed. Germany is already entering the danger zone, the effects won’t be stark for another 30 years or so perhaps, but if we delay much then there will be nothing to do to counterbalance it effectively. Demographic collapse is an issue that is way past mitigating by the time it becomes an acute problem. An ounce of prevention is not a pound or even a ton of cure, it’s the only cure. And when it starts to hit noticeably, that means you are just going over the side of the waterfall and it’s going to get a lot worse before it gets better. Korea is just starting to tip over the edge of the waterfall, in 5-10 years it is going to get much worse.

              The takeaway from the meme isn’t that we are overreacting to their situation, it’s that we are underreacting everywhere else. The real insidious issue is that in most nations having this problem, society largely panders to its politically active and (comparitively) wealthy elder base, and the best way to boost the birth rate is to shift support from them towards the young, which is politically problematic. So we are stuck in a situation where those with power have to act against their interest, in order to avoid problems that will happen far later than our brains are hardwired to care about. In short, the prognosis is very bad. Imho, the only chance most western nations have is watching things get very ugly for the elderly in Asia, and using that to scare their constituents enough to convince them that short term sacrifice is needed to avoid similar conditions for themselves. But I’d say it’s a long shot.
