South Korea is over.
0:03
This sounds brutal, but South Korea will soon start melting on all fronts – demographically,
0:09
economically, socially, culturally and militarily.
0:13
Because for decades the country has been experiencing a fertility crisis unprecedented in human
0:19
history.
0:20
And we’ve probably reached a point of no return.
0:23
By 2060, the South Korea we know and love today will no longer exist.
0:29
What will the collapse look like
0:31
and why is it now almost impossible to stop?
0:35
The (Real) Population Bomb To have a stable population you need a fertility rate
0:41
of about 2.1 children per woman.
0:43
In the 1950s South Koreans used to have 6 children on average.
0:48
In the 1980s the rate fell below 2.
0:51
And in 2023 it was 0.72 kids per woman,
0:55
the lowest ever recorded in history.
0:58
In Seoul fertility is even lower, around 0.55.
1:02
On average, about half of the women here won’t have any kids
1:06
and the other half just one.
1:08
What do these numbers actually mean in the real world?
1:12
If fertility stays as it is, then 100 South Koreans will have 36 kids.
1:17
When they grow up, they will have 13 kids, who will then have 5.
1:22
Within 4 generations 100 South Koreans will turn into 5.
1:27
If we look at today's South Korean population pyramid we see this is pretty
1:31
real:
1:31
There's only one 1-year-old for four 50-year-olds.
1:34
After 4 decades below the replacement level, the consequences were still largely invisible.
1:40
Today South Korea's population is at an all-time high,
1:42
as are its workforce and its GDP, which is still growing.
1:46
But demographics hits you like a freight train,
1:48
you hear it vaguely in the distance and then it runs you over.
1:53
South Korea is about to be hit.
1:56
Let’s time-travel 35 years into the future, to 2060,
2:00
and see what the country will look like then.
2:03
When it comes to demographics,
2:05
the most commonly used projections are those put together by the UN.
2:08
They envisage 3 scenarios: low fertility, medium and high.
2:13
But in the past,
2:14
all medium UN projections for South Korea have consistently been too positive.
2:19
Between 2022 and 2023 alone, fertility in South Korea dropped by another 8%.
2:25
So we are going to use the latest low fertility scenario,
2:29
which has been the most accurate in the last few years.
2:32
Keep in mind that we are still talking about projections
2:34
and the future is a far away land.
2:37
Ok!
2:37
Let’s do it.
2:40
In 2060 South Korea’s population pyramid will look like this:
2:44
The population will have shrunk by 30%,
2:47
16 million South Koreans will have disappeared in just 35 years.
2:52
And it will be the oldest country in human history.
2:55
One in two South Koreans will be over the age of 65.
2:59
Less than 1 in 10 will be under 25.
3:02
And only 1 in 100 will be small children.
3:06
Imagine waking up in a country where the streets are strangely quiet with no
3:10
children playing on them.
3:12
Entire cities have been abandoned.
3:14
Half of the population is elderly
3:16
and living either alone
3:18
or in overcrowded retirement homes.
3:20
With a minority of people desperately trying to keep society running.
3:25
There will be a few major consequences:
3:28
Economic Collapse In 2023 a breathtaking 40% of South Koreans over 65 lived below
3:35
the poverty line,
3:36
but in 2060 this number may seem lovely in comparison.
3:41
Today South Korea has one of the largest pension funds in the world,
3:45
worth about $730 billion.
3:48
But it is projected to stop growing in the 2040s
3:51
and be completely depleted by the 2050s.
3:54
So in 2060 pensions will have to be paid by the working population.
3:59
Estimates vary, but for a pension system to work,
4:02
the minimum a society needs is between 2 to 3 workers per retiree paying
4:06
for them with their taxes.
4:08
But even if we assume
4:09
that all South Koreans over 15 will be working in 2060,
4:13
the country will have less than one worker per senior.
4:16
Workers will be unable to stem the incredible costs.
4:20
So not only will poverty among the elderly be common,
4:22
but a big chunk will be forced to work.
4:25
Except, they may not be able to find jobs because by 2060,
4:29
the South Korean economy may have collapsed.
4:32
Broadly speaking, the size of an economy is linked to the size of its
4:36
workforce – to have a big economy you need a lot of workers to
4:39
produce a lot of things,
4:40
and a lot more people to buy them.
4:42
Today, South Korea has about 37 million people of working age,
4:46
generating a GDP of about $1.7 trillion.
4:50
But by 2060 its workforce will have shrunk to less than half,
4:54
to about 17 million.
4:56
Of course technological progress means
4:58
that productivity will be higher
5:00
and each individual will probably produce more than today.
5:03
But even if productivity keeps growing at the same rate
5:06
or more than we’ve seen in the last decades,
5:08
South Korea’s GDP could peak in the 2040s.
5:11
In other words South Korea will enter a permanent economic recession.
5:16
There are more optimistic projections that see the recession begin as late as 2050,
5:20
but they are based on the medium UN demographic scenario –
5:23
and there are no signs
5:24
that we are heading there.
5:26
Another factor in the economy is science, technology and innovation,
5:30
areas in which big leaps are typically made by young adults
5:32
and the middle aged.
5:34
Young people have fresh ideas that contribute to the wealth of society.
5:38
Significantly fewer people working also means way less tax for the government,
5:42
which will be trapped between a rock and a hard place.
5:45
On the one hand having to provide for half the population that are seniors,
5:48
on the other seeing its income diminished.
5:51
It will be forced to shut down
5:52
or cut essential services like hospitals
5:54
or social benefits.
5:56
Since infrastructure only works at scale,
5:59
smaller communities may be abandoned as the country contracts into its metropolitan areas.
6:04
And of course there won’t be enough money to invest in the future.
6:08
This is bad.
6:09
But what will happen to South Korean society and culture may be worse.
6:14
Societal and Cultural Collapse Speculating on how societies will develop is extra hard,
6:20
but there are a few pretty unavoidable trends.
6:24
Today already about 20% of Koreans live alone.
6:27
Also 20% report having no close friends or relatives.
6:31
By 2060, 50% of South Koreans aged 70 will have no siblings
6:36
and 30% will have no children.
6:38
Young adults between 25
6:39
and 35 will only make up 5% of the population
6:43
and typically have no siblings at all.
6:45
This leaves the elderly with almost no close family,
6:48
and young adults with little family and few potential friends,
6:51
especially outside of big cities.
6:53
A loneliness epidemic of epic proportions is all but guaranteed.
6:58
On top of that, South Korean culture will probably experience a huge decline.
7:03
In 2000 there were 17.5 million South Koreans between 25-45,
7:08
and they made up 37% of the population.
7:12
This was the generation that brought us K–pop, K-drama, K-food,
7:16
and many other trends that spread around the world.
7:18
In 2060 there will be just 5.6 million people in that age group,
7:23
and they will only be 16% of the population.
7:26
Many cultural traditions are already struggling
7:28
because the older generations are having trouble finding young people to pass them on
7:32
to.
7:33
As young people disappear, many traditions will die out.
7:36
Without young people, the soul of South Korean culture will shrink and wither away.
7:42
And on a personal level,
7:43
what kind of experience will it be growing up in 2060?
7:46
What will youth culture be like in a country of seniors?
7:49
Where many universities, schools
7:51
and Kindergartens are abandoned
7:53
as there are no longer children to fill them with life?
7:56
What kind of job prospects will they face and what will politics look like?
8:00
If young people don’t want to remain alone,
8:02
they will concentrate in Seoul
8:04
or a few other big cities –
8:05
or worse for South Korea,
8:07
emigrate to other countries.
8:09
Rural areas will decline
8:11
and most smaller cities will turn into ghost towns – we're already seeing this
8:15
in Japan,
8:16
which has almost 10 million abandoned houses in rural areas.
8:20
Large parts of South Korea will simply vanish and be reclaimed by nature.
8:25
Last but not least, South and North Korea are technically at war.
8:29
And they could very well still be in 2060.
8:32
Will South Korea still be able to afford to have its young men do
8:35
18 months of mandatory military service?
8:37
Today 5% of men of combat age are enrolled in the military – in
8:41
2060 it would have to be 15% just to match today's numbers.
8:46
Ok, wait – this is all a bit much.
8:48
Is there no way back?
8:50
Why There Really Is No Way Back The problem with the demographic freight train
8:55
is that once it hits,
8:56
things become irreversible.
8:58
Let’s say fertility in South Korea magically triples to the replacement rate of 2.1
9:03
children per woman and stays there.
9:05
In 2060 it will be an inverted pyramid on top of a barrel.
9:09
And there would still only be 1.5 people of working age per senior over
9:13
65.
9:14
Even in the best made up scenario,
9:16
South Korea has to pass through an unavoidable bottleneck before it will recover.
9:21
But there is also a kernel of hope here.
9:23
Yes, the situation is grim.
9:25
But at least in the long term,
9:26
recovery is possible if South Korea enacts rapid
9:29
and societal changes that make its population want to have kids again.
9:34
In 2024 births rose for the first time in 9 years – 3% more
9:38
than in 2023.
9:40
But for that to continue,
9:41
South Korea needs to face the music
9:43
and ask how they got to this point.
9:46
How Could it get that bad?
9:48
In general, as societies get richer, more educated, and child mortality plummets,
9:53
people decide to have fewer kids.
9:55
What makes South Korea special is that it's somehow supercharging all of these trends.
10:01
South Korea lifted itself out of poverty in record time,
10:04
but in doing so it developed a unique kind of workaholism and extreme competitiveness.
10:09
Although the work week is 40 hours
10:11
and the legal maximum is 52 per week,
10:14
unpaid overtime is normal for many
10:15
and the government even proposed to raise legal work time to 69 hours per
10:20
week.
10:20
Despite this, South Korea has relatively low wages and a high cost of living.
10:25
Real estate in big cities is out of reach for most people.
10:29
The cost of education is extremely high,
10:31
since families have to pay for private lessons
10:33
if they want to send their kids to a high tier college.
10:36
All of this while South Korea spends less on family benefits than most other
10:40
rich countries.
10:42
Old fashioned cultural norms make matters even worse.
10:45
Marriage is all but mandatory
10:46
if a couple wants to start a family – in 2023 only 4.7% of
10:51
babies were born to unmarried women.
10:54
Out of all developed countries,
10:55
South Korean men do just about the least share of housework
10:58
and childcare within their families.
11:01
This leaves women with a disproportionate amount of work
11:03
if they want to keep their jobs after a pregnancy.
11:06
While many men are overwhelmed by the societal expectation to be the main breadwinner
11:10
and have successful careers.
11:12
Starting a family or not is a personal decision.
11:15
And most South Koreans are deciding against it.
11:18
The bottom line is
11:19
that South Korea has created a culture
11:21
that leads to very few kids.
11:24
Conclusion Demographic collapse is not an abstract thing in the future,
11:29
it is happening right now.
11:30
And it is not just South Korea.
11:32
In 2023 China had a fertility rate of 1, Italy and Spain 1.2,
11:37
Germany 1.4, the UK 1.6
11:40
and the US 1.6 –
11:42
which sounds so much better,
11:43
doesn’t it?
11:44
Well, after four generations,
11:46
a fertility rate of 1.6 means 60% fewer new people.
11:51
A fertility rate of 1.2 means 87% fewer people.
11:55
And fertility rates are still falling, with no sign of stabilization or recovery.
12:00
The weirdest thing about all of this is
12:02
that almost nobody involved in the public discourse has truly grasped the gravity of
12:06
the situation.
12:08
The last century was utterly dominated by overpopulation narratives
12:12
and people who say
12:12
that we need more kids seem weird.
12:15
And if you do the maths,
12:16
the future just seems to be too insane to be true,
12:19
like it's hard to believe.
12:21
None of this has ever happened before.
12:23
So low birthrates are mostly discussed in the context of worker shortages – not
12:28
the existential threat to our societies,
12:31
cultures, wealth and our way of life that they are.
12:34
If we don’t take it seriously very soon
12:36
and change the DNA of our modern societies in a way
12:39
that encourages young people to start having children again,
12:42
then the rest of the century will be pretty grim – for those of
12:45
us who will live through it.
12:47
The demographic freight train stops for nobody – we finally need to realize
12:51
that it’s hurtling down the tracks right at us.
12:56
Multilayered issues like demographic change are hard to break through in our current media
13:00
landscape and easy to miss out on.
13:03
This is why we rely on Ground News,
13:06
a long-time sponsor and ally in helping find real stories of importance amongst the
13:11
jumble of information we’re confronted with every day.
13:13
In a nutshell, the app
13:15
and website gather the world's news in one place
13:17
so you can compare coverage,
13:19
see the bigger picture and make informed decisions.
13:22
Using Ground News you can see that earlier this year,
13:25
South Korea was officially classified as a superaged society,
13:28
a term that basically summarizes the effects we described in this video.
13:32
But less than 100 sources covered this development.
13:35
Interestingly, less than 20% of them are left-leaning media.
13:39
Ground News has a special feature, the Blindspot feed,
13:42
that draws attention to stories like
13:44
that which get lost amidst your personal publication preferences.
13:47
Most importantly, you can clearly compare how the issue was covered:
13:51
a government-funded source out of Slovenia for example mentioned Europe is considering immigration
13:56
as part of a solution
13:58
while Korea,
13:58
Japan and China are avoiding that aspect.
14:01
This way you can get a balanced account
14:03
and come to a conclusion for yourself.
