Population: A big problem but easy to solve

There are plenty of examples around the world where resource based economies, almost all of which do not rely on a large fraction of their population to produce the export income, are worse off with large populations. Compare the UK with Norway, both supposedly rich from North Sea oil. The UK, with a population of about 60 million, spent the income and will soon run out of oil. Norway, with less than five million people, could afford to save a huge proportion of its income in large government investment funds. Norway’s future is assured.

During the recent resources boom, Australian governments squandered the bulk of the tax revenues generated by the mining companies, at least partially, in building infrastructure for an unnecessary population explosion. As an example of this problem, consider the state of Queensland’s finances which are caught between falling resources income and the staggering costs of providing the infrastructure for a third-world rate of population growth.

In the post war period of immigration there were some sound reasons to expand Australia’s population. There was a genuine, if exaggerated, security concern which was a rational response to the near death experience that Australia encountered in World War II. There was also a concerted effort to expand Australia’s manufacturing industry which, it was argued, needed a larger population to make it viable. In the days of poor transport, we needed large internal markets.

All those factors have now changed. Manufacturing in Australia is on its knees and a growing population will not help. Mining, agriculture, tourism, and the education of foreign students are our biggest export earners and do not need a growing population.

From the environmental side, a growing population is an obvious problem. Currently we have water shortages of varying severity in all our big cities which would have been less acute if we had maintained our population at levels of 20 years ago. Melbourne would not have to contemplate encroaching into its green fringe or building a desalination plant if its population wasn’t growing. Finally, if you believe that C02 causes climate change, Australia’s population growth will make it almost impossible to achieve meaningful emission reductions. We have to reduce per-capita emissions by 50 per cent every 40 years just to keep our total emission at present levels.

Even though the problems of population growth are obvious, it is a political sacred cow that cannot be argued or debated. None of the major political parties will argue for lower immigration because they are scared of being labeled racist. Even the Greens who have a useful population policy are almost always silent on this issue. They should be arguing for lower immigration every time the Australian Bureau of Statistics population figures are released. There is also an unholy alliance between the right wing who want a growing population to feed our housing construction industry and the extreme left who want to allow the whole world to come to Australia on compassionate grounds.

The housing industry is the main beneficiary of high population growth. Every year we have to build a city the size of Canberra just to house our growth. Unfortunately this is not a productive activity, unlike building a factory, a mine, the scientific development of better farming practice, a medical breakthrough or an environmental improvement. House construction appears to be good for us because it employs people in the short term, but in the long run it will get us nowhere because it is not an investment in production. The reality is that Australia has too many people in the industry.

Although the housing industry has always been a big winner from our population policy, there is now another big player that has its snout in the immigration trough. That is our education sector. Presently, applicants who wish to migrate to Australia and have a qualification from an Australian institution get preferential treatment. This has spawned a massive industry in education which could only be described as an enormous immigration scam. In the lobby of a large Pitt Street building recently I noted that half the companies in the building were involved in either immigration advice, or education for foreign students. Many companies were doing both.

It is not only some dodgy colleges which are involved in this cash-for-visa scam. Our universities take in large numbers of students whose main aim is to gain Australian residency. We are prepared to take money from them to smooth their way through the process. Effectively selling permanent residency visas through the education system is neither ethical nor in the best interests of the country.

The population issue is an example of where this country has lost its way and is not concentrating on the big economic, environmental or social issues. We are preoccupied with global warming and the supposed imminent demise of the Great Barrier Reef even though the science on these is far from conclusive. At the same time we ignore the obvious and definite environmental problems posed by population growth: unarguably the easiest and cheapest problem to solve yet underpinning all our environmental problems.

We also refuse to contemplate nuclear power to reduce greenhouse gas emissions because, like population growth, this is another sacred cow that cannot be challenged. Economically we are prepared to sacrifice our future for the short term gain of extra foreign students in our universities and dodgy colleges, and for jobs in our non productive building industry. Socially we are not prepared to pay to train our own kids to become doctors, engineers and trades people to fill the gaps we have in our labour force. At the same time we are happy to take skilled people from developing countries which cannot afford to lose them.

With Canada and perhaps Russia, Australia is in a unique position. We have a small population and a huge country, most of which is agriculturally unproductive and unpleasant to live in. We have a relatively unspoilt environment and an abundance of mineral wealth. We also have a technologically advanced society and a good base in science and medicine. Uncontrolled population growth risks what we have. We should immediately reduce immigration to about 50,000 a year, with the medium term objective of having a zero net immigration policy; and the baby bonus should be scrapped to discourage the present rise in fertility. Because of the pipeline effect, i.e. we have a very young average population, our population will continue to grow to at least 25 million. We can then decide if we wanted to keep the population at that level or reduce it by adjusting immigration to suit.

It really is that easy.#
