A new McKinsey report highlights how low birth rates could lead to longer working years for younger generations

Basically, the report warns that if we don’t do something about it, younger folks will end up dealing with lower economic growth and a heavier burden of retirees. It’s a bit of a demographic time bomb, you know?
The authors suggest that we might need more workers, longer hours, and higher productivity to fix this mess. They even mentioned that in Germany, workers might need to clock an extra 5.2 hours a week just to keep up with living standards.
Historically, working-age people have driven economic growth and supported older generations. But now, with fewer kids being born and people living longer, that balance is really off in many developed countries.
Elon Musk has been pretty vocal about this issue, saying that population decline is a bigger threat than climate change. He’s even urged people to have kids, or humanity might face some serious consequences.
Jeremy Grantham, another big name in finance, echoed these concerns, pointing out Japan’s record low birth rates and how it’s affecting their economy. He’s worried that if this keeps up, it could destabilize human civilization. It’s a lot to think about, right?
