Thanks for the reminder. The number of people aged 65 and over will more than double and the number aged 85 and over will more than triple. We’re expected to live longer with the life expectancy of men increasing from 81.3 to 87 years and from 85.2 to 89.5 for women by 2062-63. And that’s a problem for the younger generation.

Who bears the burden of an ageing population?

 Australia’s low birth rate, limited migration and increased longevity all have an impact. The old age percentage - the number of people aged 65 and over for every 100 people of traditional working age (15 to 64) in the population - will increase from 26.6% to 38.2%.

From a tax perspective, Australia’s reliance on personal tax means workers will bear an increasing proportion of the tax burden under current fiscal policy. In a recent interview, former Treasury boss Ken Henry labelled it an “intergenerational tragedy” with personal tax growing from 11.7% of GDP to 13.5% based on current policy.

The report says that “only 12% of Australians aged 70 and over pay income tax and this age group now makes up 12.2% of the total population. This age group is expected to increase to 18.1% of the total population in 2062-63.” Wholesale tax reform will be required to prevent the growing tax burden on individuals dragging on the economy.

With economic growth expected to slow to 2.2% from 3.1% over the next 40 years, the solution will not magically arise from corporate Australia. If it was not for our high rate of inflation you would think an increase to the GST was imminent.

Demographic ageing alone is estimated to account for around 40% of the increase in Government spending over the next 40 years.

The outcome of an ageing population, as you would expect, is increased demand for care and support services that will push the Federal Budget back to a point where deficits are the norm if the current policies remain in place.

From a consumer perspective, it also means that the trend towards user-pays will only increase. As individuals, we need to ensure that we have the means to fund our old age because Government resources will be limited by increasing demand and this demand is funded by a deteriorating percentage of workers contributing to tax revenue.

It's also likely that we will need to look at how we generate income. For some that might mean working longer, for others it is value adding - creating, buying and selling assets in some form, whether that is business, innovation, or through more traditional assets such as property or financial products.

Superannuation the size of a nation

Australia currently has the fourth largest pool of retirement assets in the world, with total superannuation balances projected to grow from 116% of GDP in 2022-23 to around 218% by 2062-63. Our superannuation system will be what underwrites retirement for most Australians. At present, around 70% of people over aged pension age receive some form of Government income support.

Over time, and as our superannuation system matures, this percentage is expected to decline sharply as a percentage of GDP with Government support supplementing rather than providing for retirement (the first generation of workers with superannuation guarantee throughout their working life hit retirement age around 2058). However, the IGR points out that, “the cost of superannuation concessions will increase, driven by earnings on the larger superannuation balances held by Australians.”

The proposed tax on future earnings on super balances above $3m may not be the last. You can expect the management of superannuation to be a priority for Government to ensure that retirement savings are maximised to reduce the reliance on Government support, and to ensure that this enormous pool is leveraged for the gain of not only members, but the nation.

Growth of services

Like most advanced economies, global competition has shifted Australia’s industrial base from the production of goods to services. Ninety percent of jobs are now in services.

With an ageing population, demand for health and care services is expected to soar. People aged 65 or older currently account for around 40% of total Australian health expenditure, despite being about 16% of the population. The IGR estimates that the workforce required to support this sector will need to be twice the size of what it is now to meet demand by 2049-50.

The Government’s biggest spending pressures will be health, aged care, the NDIS, defence and interest payments on government debt. Of these, the NDIS is the fastest growing at 7% per year.

The speed of technological change is difficult to predict, and the IGR doesn’t attempt to make predictions. But what we do know is that technology has had a transformational impact on labour productivity (the value of output of goods and services produced per hour of work).

Over the last 30 years, labour productivity has accounted for around 70% of the growth in Australia’s real gross national income. But, tempering this is a slowing of labour productivity growth since the mid-2000s.

We know technological disruption is coming and the debate about the role of artificial intelligence is only just beginning. We also know that unless technology is accessible, our future will be one polarised by those who have and have not benefited from technological change.

There are two key aspects to climate change; the cost of rising temperatures, and the opportunity created by the shift to renewable energy. Temperatures are anticipated to increase by 1.5 degrees before 2100, potentially before 2040.

From 1960 to 2018, climate disasters reduced annual labour productivity in the year they occurred by about 0.5% in advanced economies. However, for severe climate disasters labour productivity is estimated to be around 7% lower after three years. With rising temperatures, floods, bushfires and other extreme weather events are expected to increase in frequency and severity.

The impact of climate change spelt out in the report is sobering with disruptions and changing patterns impacting agriculture, tourism, recreation and industries that rely on labour intensive outdoor work.

On the positive side, Australia could benefit from new “green” industries, such as hydrogen and other clean energy exports, critical minerals and green metals. It is also likely to drive new, innovative ideas as businesses invest in and develop low emissions technologies, providing a source of future productivity growth in a more sustainable economy.

Australia’s potential to generate renewable energy more cheaply than many countries could also reduce costs for both new and traditional sectors, relative to the costs faced by other countries.

Australia relies on open international markets. Trade disputes and military conflicts pose an external threat to Australia’s economy and well being. While the IGR cannot predict the nature of geopolitical events, it notes the importance of investing in national security, presumably this includes cybersecurity, ensuring access to international markets, and deepening regional partnerships to reduce supply chain vulnerabilities.
