Australia has the world's most successful economy. Politics could mess it up

The last time Australia suffered a recession, the Soviet Union still existed and the internet did not. A U.S.-led force had just liberated Kuwait, and almost half the world's current population had not yet been born.

Unlike most of the Asia-Pacific region, Australia was left unscathed by the Asian crash of 1997. Unlike most of the developed world, it shrugged off the global financial crisis of 2008, and unlike most commodity-exporting countries, it weathered the resources bust, too.

No other rich country has ever managed to grow so steadily for so long. By that measure, at least, Australia boasts the world's most successful economy.

Admittedly, as Guy Debelle of the Reserve Bank of Australia points out, this title rests on the statistical definition of a recession as two consecutive quarters of decline. Had the 0.5 percent shrinkage of the fourth quarter of 2008 been spread across half a year, he notes, there would be no record. Yet by other measures, Australia's economic performance is more remarkable still.

Whereas many other rich countries have seen wages stagnate for decades, Australia's have grown strongly, albeit less steadily in recent years. In other words, a problem that has agitated policymakers — and voters — around the world, and has been blamed for all manner of political upheaval, from European populism to the election of Donald Trump, scarcely exists in Australia.

And that is not the only way in which Australia stands out from its peers. At a time when governments around the world are souring on immigration, Australia has been admitting as many as 190,000 newcomers a year — nearly three times as many, relative to population, as the United States.

More than 28 percent of the population was born in another country, far more than in other rich countries. Half of all living Australians were born abroad or are the child of someone who was.

Nearly 30 years ago, the government of the day overhauled the pension system. Since then workers have been obliged to save for their retirement through private investment funds. The modest public pension covers only those without adequate savings.

Australia's health care system is also a public-private hybrid. The government provides coverage for all, by paying clinics and hospitals a set fee for every procedure they perform. Those who want more than the most basic service must pay a premium. The government encourages people to take out insurance to cover the gap between the reimbursement that it provides practitioners and the rates most of them charge the public. As with pensions, everyone gets looked after, but the government bears only a relatively small proportion of the cost — an arrangement that remains a distant dream in most rich countries.

Not all is perfect, of course. A common concern is that the economy relies too heavily on China, which is the biggest buyer of Australian minerals, the biggest source of tourists and foreign students, even the biggest consumer of Australian wine. People worry that if the Chinese economy falters, it will drag Australia's down with it. Another fear, somewhat at odds with the first, is that China might try to use its economic power to blackmail Australia into weakening its U.S. alliance.

There are glaring domestic problems, too. The appalling circumstances of many Aboriginals are a national embarrassment.

Even more alarmingly, global warming is making an already grueling climate harsher. Rainfall, never reliable, is scarcer and more erratic in many farming regions. Over the past two years unusually hot water has killed a third of the coral on the Great Barrier Reef, one of the country's greatest natural treasures.

Some see the failure to settle on a coherent climate policy as a symptom of a deeper political malaise. Australia used to have long-lived governments. Between 1983 and 2007, just three prime ministers held office — Bob Hawke and Paul Keating of Labor, and John Howard of the Liberals.

Yet, since 2007, the job has changed hands six times. A full term is only three years, but the last time a prime minister survived in office for a whole one was 2004-2007. It is not usually voters doing the deed, but fellow MPs who dispatch their leader in hope of a boost in the polls.

For those who consider Australia's unequaled economic performance the result, at least in part, of farsighted decisions made 30 years ago, the current choppy politics seem like a harbinger of decline.
