Joeri Schasfoort delivers a sobering reality check on the global economy, arguing that the coming population crisis is not a distant theoretical threat but an immediate structural shift already reshaping national destinies. While most analysis fixates on fertility rates alone, Schasfoort's distinctive contribution is his reliance on the "dependency ratio" to explain why a young population like Africa's isn't yet an economic boom, and why China's decline will hit harder and faster than Japan's. This is essential listening for anyone trying to understand why the center of economic gravity is moving not just to India, but eventually to a continent we have long underestimated.
The Myth of Economic Decline
Schasfoort begins by dismantling the common narrative that Japan's economic stagnation since the 1990s was a policy failure. He reframes the data through a demographic lens, noting that "Japan's low economic growth was not a sign that they mismanaged their economy. It was simply a consequence of so many workers leaving the workforce." By isolating hours worked from productivity, he reveals that Japanese workers actually became more efficient per hour than their American counterparts, even as the total workforce shrank. This distinction is crucial: it suggests that the coming "Japanification" of Europe and East Asia is an inevitable mathematical outcome, not a political mistake that can be fixed with lower interest rates.
The author's prediction that this trend will spread is stark. "My second prediction is that as the global population crisis intensifies, we will see more and more countries hit a government debt limit, that will either result in a debt crisis or dramatic cuts to the welfare state." This argument lands with force because it connects the abstract concept of aging populations to the concrete reality of sovereign debt ceilings. Critics might note that technological advancements in automation could theoretically offset the loss of human labor, potentially delaying the debt crisis Schasfoort predicts. However, the sheer scale of the demographic cliff in China and Europe suggests that productivity gains alone may struggle to keep pace with the shrinking tax base.
The Dependency Ratio Trap
Perhaps the most counterintuitive insight in the piece is the explanation of why high fertility does not automatically equal economic growth. Schasfoort explains that "a big group of children is an economic burden as well," meaning that only societies with a high ratio of workers to dependents enjoy a "demographic dividend." He uses this framework to explain why China's miracle coincided with its one-child policy and why Africa, despite its massive youth population, has not yet seen an economic explosion. "Africa may be young, but so far its economies are not benefiting from that at all," he writes, pointing out that Kenya's dependency ratio currently mirrors Japan's.
Only societies that have many workers compared to children and the elderly have an economic advantage, a so-called demographic dividend.
This reframing is vital for investors and policymakers who often conflate population growth with market potential. The timeline Schasfoort presents is sobering: India's dividend is just beginning, but Africa's will not truly kick in until around 2050. "China's rapid decline and Africa's rise will cause the economic center of the world to shift towards Africa," he predicts, but only after a long lag period where the continent remains a net burden rather than a net gain. This nuance separates his analysis from the usual hype about Africa's "rising star" status.
The Migration Imperative
As the economic centers shift, the flow of human capital must follow. Schasfoort identifies a "migration hump," where people are most likely to leave a country once it becomes slightly richer, but stay once it becomes truly wealthy. He argues that Africa is currently climbing this hump, creating a perfect storm where aging economies in Europe and Asia desperately need labor just as Africa's population explodes. "Migration from Africa to some rich nations will change the world even though I cannot predict exactly to which countries they will move due to politics," he states, acknowledging the friction between economic necessity and political will.
The author's confidence in this trend is tempered by the volatility of public sentiment. "Whether or not countries want to use it, that will be up to politics," he admits, noting that Japan is already being forced to open its borders for care workers. This section highlights the tension between the cold logic of demographics and the hot emotions of nationalism. A counterargument worth considering is that automation might reduce the need for low-skilled migration, potentially breaking the link between aging populations and labor shortages. Yet, as Schasfoort notes, the sheer volume of workers leaving the workforce in places like China and Germany makes a purely technological solution unlikely to be sufficient.
The Limits of Prediction
Despite his confidence, Schasfoort offers a rare moment of humility regarding the data itself. He warns that the United Nations' projections may be overly optimistic about fertility rates bouncing back, citing evidence that "once fertility rates start to drop, they keep dropping." He points to the US and South Korea as examples where UN models assume a recovery that current data does not support. "Those years might be off as well," he concedes regarding the timeline for Africa's rise, noting that data reliability in China is also questionable. This admission strengthens his credibility; he is not selling a deterministic future, but rather a probabilistic one based on the best available, albeit flawed, evidence.
My fifth prediction is that the years of prediction number three will be wrong.
This self-correction is the piece's most sophisticated move. It acknowledges that while the direction of the trend is clear, the speed remains uncertain. If fertility continues to plummet faster than models predict, the economic center of gravity could shift even more abruptly than Schasfoort anticipates, leaving developed nations with even less time to adapt their immigration and pension systems.
Bottom Line
Schasfoort's strongest argument is his use of the dependency ratio to demystify why population growth does not guarantee prosperity, a nuance often lost in mainstream economic reporting. His biggest vulnerability lies in the assumption that political systems will eventually succumb to the economic imperative of migration, a leap that history suggests is far from guaranteed. The reader should watch for the next decade of fertility data in East Asia and the US, as a continued drop below replacement rates will accelerate the timeline for the global debt crises he predicts.
