This topic is absolutely fascinating. Here are all the ingredients for the bomb: - Demography department: a) fertility, b) pension systems, the link between economic growth, population growth, and productivity growth (how can you have a safe pension system anyway without economic growth? will people have access to safe investments, if all safe investments simply track economic growth? can we have economic growth which is based solely on productivity growth if population is contracting?) - Climate warming department: lifetime CO2 emissions per human being, and environmental impact. - The perception of all the above. If most people believe than the above problems are more severe than they are, due to amplification (schooling, social media, institutions, etc), then they will want to have even less children.
