It's interesting seeing how humans are deciding to forgo one of the most innate patterns of life itself, passing their own genes via these phenomenons. It's almost as if it's a 'invisible hand' regulating the population by cornering people to prefer an achievable amount of pleasure (retire early, travel, etc) by trading it for not having offspring. This also relates to all the news about the rise of 'despair deaths'. No jobs, no way to ensure offspring a quality life, therefore game over for those genes. It is a big claim that these communities don't have kids, I would want more evidence of that before jumping to conclusions but if that's the case it's pretty crazy to read about.
