“How can we overcome Korea’s population crisis?”
Survival strategies for the ultra-low birth rate era proposed by Professor Kim Tae-yu, a historian of civilization at Seoul National University.

There is one video that has captured the attention of viewers around the world.
This is a video titled 'South Korea is over' released by the German science content channel Kurzgesagt.
Based on the shocking figure of a birth rate of 0.7, the video presents a pessimistic outlook: by 2050, Korean society will be reorganized around the elderly, and the industrial and cultural assets accumulated to date will be virtually unsustainable.
The video garnered over 12 million views in just one month after its release, creating a huge stir both domestically and internationally.

Should we simply stand by and endure this situation? A book titled "A Country Without Youth" has been published to answer this question.
This book is a development of "A Country Without Retirement," published in 2013 by Professor Kim Tae-yu, a historian of civilization at Seoul National University, to suit the situation in 2025. It presents the fundamental causes of Korea's ultra-low birth rate, the flawed policies of the past, and solutions.
Professor Kim Tae-yu, who has studied the principles of national development throughout his life, diagnoses in this book that South Korea is facing both the greatest crisis in its history and the greatest opportunity in the history of civilization.
The question I pose is simple yet fundamental.
“Is it really inevitable that it will collapse like this?”

“The diagnosis was wrong from the start.”
Why it failed even after spending 380 trillion won

Since 2005, the government has invested over 380 trillion won in an effort to address the low birth rate.
A variety of systems, including childcare leave, childcare allowances, and childbirth incentives, were introduced, and a system that was outwardly similar to a welfare state was established.
However, the birth rate did not rebound, but rather fell to the lowest level in the world.
What could have been the problem?

The author finds the core cause of the policy's failure in 'diagnosis errors.'
The birth rate of 1.4 and 0.7 may seem like just a difference in numbers, but the social context is completely different.
1.4 may be a recoverable level, but 0.7 indicates an irreversible structural collapse.
However, the Korean government has either copied the response measures of advanced countries overseas or relied on ineffective populist policies.
However, the younger generation does not decide to get married and have children based on ‘a few pennies.’
Because the foundation of life has collapsed.
This book asks the question again from the very beginning.
What makes Korea's ultra-low birth rate different? And why doesn't conventional methods work?

"The problem isn't the birth rate, it's the dependency ratio."
The 20-30 generation who cannot receive the national pension and an unsustainable society

The fact that the birth rate is low does not in itself shake the sustainability of society.
The problem is the demographic reversal phenomenon, where the youth population is decreasing while the elderly population is rapidly increasing.
In other words, Korean society is rapidly being reorganized into an 'inverted pyramid' structure, and the resulting 'worsening of the dependency ratio' is causing a critical crisis.

Dependency ratio refers to the number of economically inactive people that one working person must support.
In the past, three people supported one person, but in the future, we will enter a society where one person will have to support two or three people.
This has a domino effect not only on pension finances, but also across all sectors, including education, healthcare, local economies, and the housing market.
Many small and medium-sized cities in the provinces have already entered a phase of population decline, and the younger generation knows that the depletion of the national pension coincides precisely with their own retirement.
The author argues that:
Now, the goal of national policy should be not to boldly 'raise the birth rate' but to 'lower the dependency ratio'.


“50% concentration in the metropolitan area”
Structural competition that strangles young people's lives

Korea is one of the most competitive societies in the world.
Behind this lies the structural problem of ‘concentration in the metropolitan area.’
More than half of the total population is concentrated in Seoul and Gyeonggi Province, which is an extreme level compared to other advanced countries such as Japan (28%), France (18%), and the United Kingdom (13%).
This concentration is not simply a matter of administrative convenience; it is a real factor that is squeezing the lives of young people.
All resources, including jobs, education, culture, and medical care, are concentrated in the metropolitan area, and the competition for survival here is becoming increasingly fierce.
Amid high housing prices, soaring rents, and the burdensome cost of education and living, young people are giving up on dating, marriage, and having children.

Moreover, this structure is self-replicating.
As young people flock to the metropolitan area, companies move their headquarters back to the metropolitan area to follow the talent.
Regions that lose jobs lose more of their population and ultimately face extinction.
The government and local governments are trying to solve the problem by expanding the housing supply in the metropolitan area, but this only serves to reinforce the concentration of population in the metropolitan area, leading to a "repetition of imbalance."
Professor Kim says.
“The right policy should work toward reducing the concentration of population in the metropolitan area.”

"We need a society of aunts and uncles."
For a society where youth and old age coexist

As the first strategy to resolve the two axes of worsening dependency ratio and concentration in the metropolitan area, Professor Kim proposes a 'double-cropping society.'
He points out that while the introduction of foreign workers, extension of the retirement age, and introduction of artificial intelligence are being discussed, it is difficult to see results in the short term and the costs are high.
Instead, he emphasizes that we should focus on the potential resources that can be utilized immediately, namely the 'second career life' of the middle-aged generation (ages 55-74).
In the past, working for 30 years and retiring for 20 years was the common life structure.
But now, we live in an era where we have to work for 20 years and live for 30 to 40 more years.
If we do not change our systems and social perceptions to accommodate this change, the middle-aged generation will be reduced to an inefficient population of “healthy and capable people who do nothing.”

The author explains this by citing concepts from developmental psychology, namely the theory of fluid intelligence and crystallized intelligence.
Fluid intelligence, including problem-solving skills and creativity, peaks in the late 20s and then declines, while crystallized intelligence strengthens over time through experience and knowledge accumulation.
He suggests that young people should pursue creative and technical fields that require fluid intelligence, while older people should pursue fields that require crystallized intelligence, such as counseling, administration, education, and caregiving.
The dual-generation society is not simply about re-employment of the elderly, but rather about creating a structure that allows for division of labor rather than competition between generations.
The book also presents specific guidelines for corporate personnel strategies, government policy directions, and individual life planning to achieve this goal.

"In the era of the Arctic Route, we must create a second megacity in Busan, Ulsan, and Gyeongsang Province."
The Korean Peninsula's first and last opportunity has arrived.

The second solution is to build a 'second megacity' to break the unipolar system of the metropolitan area.
I think the best place is Busan, Ulsan, and Gyeongnam, or the Buulgyeong region.
The decisive reason is the historical change in civilization called the ‘Northern Sea Route’.
Due to global warming, the Arctic sea route is gradually opening up, and it is expected that year-round navigation will soon be possible.
Buulkyung, located on the Korea Strait, a key point in the Northern Sea Route, is strategically positioned to develop into a new maritime economic hub in an era of shifting global logistics flows.
This is not simply a regional development, but an opportunity to become a key player in the global supply chain.

Until now, balanced national development has attempted to develop the entire country evenly, but the effect has been minimal.
Professor Kim emphasizes that “a strategy of selection and concentration” is now necessary.
Only by fostering an economic and industrial center on par with Seoul in the southeastern part of the Korean Peninsula can we create a structure where young people can live, work, and love in the provinces.
If Busan, Ulsan, and Gyeongnam establish themselves as a hub port on the Northern Sea Route, a bipolar system could be formed between the metropolitan area and Busan, Ulsan, and Gyeongnam.
This could be a decisive strategy to overcome the two challenges of population crisis and low growth simultaneously.

There is no future in a society where young people disappear.
"A Nation Without Youth" is not simply a book about encouraging childbirth, but rather a guidebook containing sustainable survival strategies for the society of the Republic of Korea. It is a must-read for politicians, the media, educators, policymakers, and all citizens concerned about the future.
