Against all evidence there is a widespread belief that the Coalition is more competent in economic management than Labor. In part this is because it has appropriated the language of economics to suit its own ideological agenda.

For hundreds of years people held the idea that cholera and the black death were caused by a miasma in the air, even in the face of accumulating evidence of the workings of person-to-person bacterial infection. Millions were to die because that idea was so hard to dislodge.

In the realm of Australias political and economic ideas there is similarly an enduring belief, in defiance of accumulating evidence, that the Liberal Party (or more generally the Coalition), is much more capable of handling the economy than Labor.

Its a belief not supported by data on Australias economic performance, or by the informed views of independent economists. Nor, at first sight, do electors seem to have much faith in the Coalitions economic priorities when they are polled on economic policies that count in peoples lives. When people are asked which party does better in looking after the interests of working families, or handling the economy in a way that helps you and people like you the most polling consistently sees Labor well ahead of the Coalition

But when people are asked which party can best handle the economy the Coalition dominates. There is some gap between the economy as people experience it and the economy as some abstract concept. Its as if the economy is some god that must be appeased, even if its behaviour is beyond human ken.

Our common sense may tell us that there is something wrong when, no matter how hard we work, the fruits of our labour are collected by others. We may struggle to find how we have benefited from our electricity suppliers and roads being sold to private investors. We may be puzzled by the contrast between the private affluence of corporate high flyers and the financial struggle faced by teachers, nurses and others who do tangibly useful work. We may not understand why high electricity prices are bad while high housing prices are good.

It is not for us, mere mortals, to understand these things, however. The economy is a god who moves in mysterious ways ways that can be understood only by the priests in the sacred temples the Soviet-style buildings on King George Terrace in Canberra and the bankers towers in Melbourne and Sydney.

Trust us is the paternalistic message from Liberal politicians and their acolytes in Treasury: we know that we must cut taxes and government spending, keep unions suppressed, and sell public assets. You may say youd prefer better schools and hospitals to a tax cut, but we know better.

And like fundamentalist preachers who warn of unspecified suffering to be endured by those who might stray, they raise fear about the horrors of a Labor government, without ever explaining what those horrors may be.

In this task one of the Coalitions main weapons is language taking everyday terms and ideas and twisting their meanings. The Coalitions appropriation of language has successfully led Australians to believe in its economic competence. As Orwell pointed out, politicians shape language for their own purpose.

Just as totalitarian communist regimes appropriated terms such as freedom-loving, solidarity and comrade, so too has the Coalition taken terms such as aspiration and individualism, shaping them to align with their own ideology. Even technical terms such as economic growth have come to have ideological normative meaning economic growth, whatever its source, becomes something unquestionably good, and every job, whatever its pay and conditions, is a good job. There are echoes of Orwells Animal Farm when the Coalition talks about debt: government debt bad, private debt good.

This appropriation of language goes back a long way. In the Australian political arena its most stark manifestation was Menzies use of the term liberal to describe a party that has always had a bent to authoritarianism and paternalism. But it has become more calculated and refined over recent years, particularly as the Coalition has moved away from articulating a policy platform (John Hewson was the last Coalition leader to try that) and towards employing the dark arts of advertising in the task of impression management an impression about economic competence, preferably encapsulated in a three-word slogan.

What the Coalition offers doesnt have to be true or even credible; it simply has to capture ones uncritical facilities in those critical moments when people cast their votes. Its the political version of the tactic once used by door-to-door insurance and vacuum-cleaner salesmen.

The bunch of people who make up the Coalition havent achieved this on their own. Worldwide many progressives and those who still describe themselves as left have abandoned the hard discipline of economics in favour of identity politics, leaving the economic high ground to be occupied by conservatives. (This abandonment of the economic high ground is something my colleague Miriam Lyons and I cover in our work Governomics.) In Australia the Coalitions task is eased by the fact that it is in contest with a reforming party: a party of reactionary conservatism can appeal to fear and risk-aversion, as the Coalition does when it unashamedly defines its _raison detre_as to keep Labor out of office. No need to say anything more; in fact it has nothing more to say.

In this task it is helped immensely by its appropriation of language using language so appropriated to define public ideas on its preferred terms.

Over the next few weeks I will write a number of short articles for Pearls and Irritations, dealing with one word or phrase at a time, suggesting how these terms can be taken back and used by those who seek to promote a more inclusive, sustainable and just form of economics_._

As the Methodist philosopher George Whitefield said, its a pity that the devil has all the best tunes. The devil should not be allowed to have all the best language.
