Browsing social media, it’s apparent that people are quick to point out problems in the world, but what I see less often are suggestions for how to solve them. At best, I see vague ideas that might solve one issue but introduce new ones, which are rarely addressed.
Simply stopping the bad behaviour rarely is a solution in itself. The world is not that simple. Take something like drug addiction. Telling someone to just stop taking drugs is not a solution.
It’s not exactly speculation. The birth rate in much of developed countries is well below the replacement rate. Population decline is already happening in some countries. Looking at current demographic charts shows that the number of elderly people is growing fast, while younger generations are shrinking. With fewer children being born, there will soon be much less workers to support a lot more retirees. Pension systems, mostly designed for growing populations, will be in real trouble as fewer people pay into them and more people are taking money out.
