1
This is Taiwan, a heavily disputed territory off the coast of mainland China
2
that is home to 23.5 million people and some of the most important industrial centres in the world.
3
Don't worry, this is not yet another video about Chinese
4
and Taiwanese hostilities and how it could be the catalyst for a major war between global superpowers.
5
It's instead about a trend that, while not as attention-grabbing, could be just as devastating for most of the world.
6
Taiwan today is the second richest major economy in Asia, following only just behind Japan, which it should overtake in the next few years if current trends continue.
7
It is clearly an advanced economy, after making the transition from a poor agrarian makeshift settlement and a military dictatorship that only officially ended 35 years ago.
8
Taiwan's story of transitioning from an agrarian economy to a low-cost manufacturing centre, and then finally onto becoming an advanced centre of world-leading industries is not unique.
9
Other countries in the region followed very similar paths in the last decades of the 20th century.
10
South Korea, Singapore, Japan, even certain regions within mainland China, all became what economists would broadly call advanced or developed economies.
11
Taiwan is interesting because it really was one of the last major economies to make that jump.
12
And today, more
13
and more of the fast-growing economies from around the world are
14
struggling to make the transition from a developing economy to an advanced economy.
15
There are even examples like Brazil
16
that arguably became the first country ever to go from being an advanced economy back to being a developing economy.
17
Outside of unique situations like this one, the general trend is that less and less countries are making
18
that final step to become fully-fledged advanced economies and are getting stuck dealing with endless problems in the developing stage.
19
Already this year we have made videos about Sri Lanka, Pakistan and even China that are all lurching from one economic problem to the next to the next.
20
Now there are endless reasons as to why rich countries are rich and poor countries are poor, but one of the biggest ones is an economic process known as brain drain
21
which has the potential to solidify countries' positions in the global economy
22
and make it almost impossible for anybody else to join the ranks of the 30 or so existing advanced economies.
23
So, what is brain drain and why is it getting worse?
24
How is brain drain making rich countries richer and poor countries poorer?
25
And finally, is there any way for the developing countries to stop this from happening.
26
There's no specific definition of what an advanced economy is or is not.
27
Economists roughly agree that it's a country with a GDP per capita at least above $20,000 per year at the absolute minimum, a country with advanced and highly technical industries,
28
a well-functioning and fairly regulated market system, and a good score on the Human Development Index.
29
A combination of all of these factors is kind of important, and that's why institutions like the IMF would classify Spain as an advanced economy,
30
but not Brunei, even though Brunei has had a GDP per capita 50% higher than that of Spain's.
31
In fact, the IMF is really the only agency that specifically defines individual countries by labelling them as advanced,
32
emerging, or low income, and you really have to go digging to find those classifications.
33
To most economists, an advanced economy is one of those things where you know it when you see it, and I think it's important to mention
34
that as we try to make sense of what is stopping other countries from reaching this ill-defined status.
35
Braindrain is the process of highly educated
36
and productive participants in an economy leaving their home country to pursue better opportunities in another country.
37
This move can be motivated by better paying opportunities, a better lifestyle, or be driven by people leaving their home countries to avoid violence, corruption or persecution.
38
Overwhelmingly the most productive members of economies around the world are moving from developing economies and moving to advanced economies.
39
I am massively generalising here
40
but advanced economies are normally nicer places to live with lower rates of violence and higher paying jobs.
41
An engineer in India earns an average salary of 800,000 rupees which is about 10,000 US dollars.
42
In India that's actually a decent salary, but if they can take those expertise and get qualified as an engineer in the United States, they would potentially be earning ten times that amount or more.
43
An advanced country like the USA, while it has its problems, is also far less crowded and polluted than most areas of India, so if it is an opportunity that is presented to them,
44
a lot of people from India and a lot of other countries will take it.
45
This hurts the countries they are coming from because they lose their most productive workers, the workers that will pay the most tax,
46
produce the most value, and have the highest chances of of driving innovation to make the country wealthier.
47
They also lose these workers right as they stop being an economic burden, which I know is a very mean thing to say about children and students, but that's what they are.
48
They take more money from the economy than they contribute until they go on to be workers.
49
After their working careers, they once again become an economic burden in their old age.
50
This is normally an investment worth making, either for the government or the children's families, because in undeveloped economies, children will go on to look after their parents while they can no longer work,
51
and in developing in advanced economies, the children will go on to produce way more value in
52
their working lives than the government lost to educating them
53
and potentially losing out on their parents' taxable incomes while they looked after them.
54
But the distinction of who pays and who benefits from children is different in these different economies.
55
For undeveloped countries with little to no government welfare or support systems, individuals bearing the cost of having children is worth it
56
because the children often directly work alongside their parents on farms or in businesses.
57
children in these countries is also very cheap, so they are effectively making a low-cost workforce and a retirement plan all in one.
58
Alongside other cultural factors, this is why most low-income economies have such young populations with so many children.
59
For high-income countries, the cost benefit of having children is reversed.
60
Raising children is very expensive and often requires parents to leave the workforce for an extended period of time.
61
There are also laws in most of these countries against using children for labour, even in family businesses, and there is no expectation
62
that the children will financially support their parents in their old age
63
because there are already alternative systems in place to do that
64
because of this almost every major
65
and developing economy around the world today is dealing with some
66
kind of demographic issue where their people are simply not having
67
enough children to continue this cycle of young generations looking out for the elderly
68
if a majority of people get too old to work it
69
will put a significant strain on the few young people who still can either directly as more
70
and more of the workforce gets dedicated to looking after the elderly
71
or indirectly as young workers are forced to pay high taxes to cover the costs of looking after an aging population.
72
This is already happening.
73
The labour force participation rate in most countries is already falling
74
as people are opting out of the workforce earlier than what economists assume.
75
These figures also don't count for the growing population of people over the assumed working age that will require even more care.
76
Low income and developing countries are going to feel this effect the most
77
because a a higher portion of their jobs involve physical labor, but unlike service space jobs in offices, just can't be done by people that are too old or frail.
78
High income, advanced economies also have another advantage, which is why they stay rich.
79
While low-income and developing economies only get the drawbacks of brain drain, which accelerates the problems they have with ageing populations,
80
rich countries benefit from it by being in the sink that those brains drain into.
81
Which is just terrible imagery, but you get what I'm saying here.
82
Rich countries that are desirable destinations to live
83
and work will get their pick of skilled young workers who want to move there to start a better life.
84
Most advanced countries can pick how many skilled workers they want to enter their economy simply by increasing
85
or decreasing the amount of skilled worker visas they give out.
86
After the global pandemic and record unemployment rates combined with low labour force participation, a lot of governments are opening up to record numbers of skilled migrants.
87
Not only will these workers help to fix all the problems of an aging population, they can also act as a form of economic stimulus.
88
People moving to a new country will need to buy a lot of new stuff to get themselves established.
89
New cars, new furniture, new phones and internet plans and of course a new house and everything that comes with it.
90
Whether they are renting or buying, a skilled migrant will be bringing money from their home country into the host country to stimulate the domestic economy.
91
One area where this is most apparent is in schooling.
92
One of the primary paths to residency for most people moving from a low income
93
or developing economy into an advanced economy is through student visa programs.
94
People that have completed a university degree in a developed country are more likely to be successful
95
if they apply for a working visa after they graduate
96
because the host country will recognise their degree
97
and be confident of the applicant's language skills and ability to be productive enough to at least pass university exams and assignments.
98
University degrees in most schools and advanced economies are significantly more expensive for international students
99
because there are no government pricing controls combined with lots of demand, so those students provide a great source of revenue to these centres of education.
100
This is not without its problems.
101
In my own home country of Australia, education is one of the largest exports we have.
102
We receive more money from abroad to pay for university fees than we do for petroleum or natural gas.
103
Because this is so lucrative, there has been a trend to make sure that international students get what they pay for no matter what, which is a university degree.
104
This has caused multiple scandals where professors were pressured into passing poorly performing international students just to make sure
105
that the university kept a good reputation for more international students in the future.
106
This is not a problem by any means unique to Australia either, and universities around the world are going to struggle to balance the temptation of easy money from international students
107
and their families who are willing to pay almost anything for
108
a free stepping stone into a life in an advanced economy and academic integrity.
109
International students also take the places of local students who might have wanted to attend a university
110
but missed out because their grades weren't high enough to compete with their local cohort as well as students from other countries.
111
This wouldn't be such a big problem if it was totally fair, because nobody is owed a place in these schools, and if local students don't meet the standards of enrolment they shouldn't be let in just
112
because they were born in the same country the university operates in.
113
But again, there have been multiple instances where international students
114
that do make the cut arrive for their first semesters with little to no language skills and questionable academic performance.
115
If students have been let in from abroad at the expense of local students just because they pay more money, then that is obviously a problem.
116
These significant small scale issues aside though, if we look at this process from a macroeconomic perspective, It's almost the perfect way to introduce skilled labour into an economy.
117
The country receiving international students gets direct stimulus from abroad, which funds their research institutions.
118
It also gets stimulus as those students need to pay for their everyday living expenses like housing, food and entertainment.
119
A lot of countries' student visa programs will allow students to work part-time jobs while they're studying, but even still, most of the money to cover these expenses will be coming from their family
120
or personal savings back at home.
121
Even if they do take a part-time job, that can often help the host country
122
because they will normally be working the unskilled and not particularly well-paid jobs that people don't care about missing out on.
123
As soon as they graduate from university, if they then enter the workforce in the host country they are starting out literally at the very beginning of their careers, so they are maximising the time that they can add value
124
and pay taxes to a country that did not have to support them while they were children.
125
This also ensures that advanced economies get the best
126
and brightest workers to progress innovation to make sure
127
that their industries are more advanced and competitive than any alternatives that come from developing economies that lose their most promising innovators.
128
So if this is such a problem that is already stifling the growth of dozens of countries around the world, how can economists stop it?
129
The simple fact is
130
that advanced economies are almost always going to be more desirable places to live and work than developing economies.
131
Not only because they offer higher incomes to workers, but also because they generally have lower levels of corruption, crime and pollution, while also having better access to healthcare,
132
education and other public utilities.
133
Again of course this is a generalisation.
134
There are examples of certain developing economies that beat out certain advanced economies in these factors, but it generally holds true,
135
and that's the first thing that can be done to at least slow brain drain.
136
People will be less likely to move abroad if living conditions at home are good, so making sure a developing country is a good place to live is a very important factor in determining whether
137
or not it will make it to become an advanced economy.
138
Of course getting rid of pollution, crime and corruption while providing better public services is much easier said than done, but it does highlight the importance of people,
139
macroeconomics where the focus tends to be on big industries and trade deals.
140
The other more direct approach countries can take is to invest heavily into industries
141
that have the potential to make them advanced economies.
142
South Korea, Japan and Taiwan, some of the most successful economies of the last five decades,
143
all got started with strong government programs designed to build out world leading technical industries in the country.
144
This is distinct from low cost manufacturing in places like China or India, and even from services in places like the Philippines.
145
These are industries that are controlled by the greatest innovators, not the lowest bidders.
146
Japan still designs and manufactures a lot of the world's most advanced electronic devices, South Korea is home to dozens of globally competitive companies,
147
and by now I'm sure that you're all aware of just how important Taiwan's industries are to the global economy.
148
Investment in these industries often involves paying lots of money to people
149
so that they move to less desirable countries and provide their expertise for long enough to get the industry off the ground.
150
It's also a risky endeavour with no guarantees of success, and it and it could just as easily take up a lot of government money
151
that could have been spent on providing public services and getting rid of crime, corruption, pollution, and all of the other things that made people want to look abroad for a better life to begin with.
152
This subject was actually suggested by a commenter on a community post we made asking for video ideas.
153
The team and I had been doing background research on Braindrain
154
and its effects on developing economies for a while
155
because it was important to a lot of national economies that we'd explored over the past few months.
156
But this comment was what made us decide that it probably needed a video all of its own.
157
So if you have an economic topic that you think deserves a video, make sure to let us know.
158
Thanks for watching mate.
159
Bye.

シャドーイングとは?英語上達に効果的な理由

シャドーイング(Shadowing)は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的:ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影(shadow)」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
