Something highly significant has happened in just the past week: it's become clear the tide has turned in our politicians' demonisation of budget deficits and debt. What used to be anathema is so no longer.
Predictably, it's happened not because the pollies have seen the light, but because they've been mugged by reality. In consequence, the Grattan Institute's John Daley may well be right in saying we face a "decade of deficits".
That's not to say we'll hear no more of unpopular cuts in government spending, however. We'll get more of those in Wayne Swan's budget next month, and a lot more should Tony Abbott win the election in September. But these will be about stopping the parties' expensive election promises making the budget deficit even bigger, not about getting back to surplus. In Abbott's case it will involve cutting away Labor's favourite programs and replacing them with his own.
I won't be sorry to see an end to the economically illiterate nonsense the pollies have been spouting for so long about the evils of deficits and debt. That's because there are times when deficits are exactly what governments should be running and when modest levels of debt are nothing to worry about.
But, equally, there are times when surpluses are just what governments should be running. And we'd have to be terribly unlucky for such times not to return well before another 10 years have passed.
Governments have been agonising over the need to restrain budget deficits for almost all of the four decades I've been observing them - usually without much success. But the fashion for outright demonising of deficits began when Peter Costello became treasurer in 1996, claimed to have inherited a "budget black hole" from his Labor predecessors but, after one super-tough, promise-breaking budget, soon found the budget had swung back into surplus, only to stay there for the rest of the Howard government's 11-year term.
The steady stream of surpluses, combined with the proceeds from privatising Telstra, allowed him to eliminate the manageable debt he had also inherited. Costello used this experience to argue incessantly that deficits are always bad and surpluses always good, with the Liberals the party of surpluses and Labor the party of deficits.
When the global financial crisis hit in late 2008 and pushed the budget back into deficit, with Kevin Rudd's stimulus spending adding to that deficit, the immediate effect of the crisis on our economy proved surprisingly modest and it suited both sides to claim we had escaped recession.
Labor claimed this proved what a good economic manager it was, whereas the Libs used it to prove Labor's stimulus spending was unnecessary and wasteful, leaving our children and grandchildren weighed down by horrendous government debt.
The more years have passed with unemployment, inflation and interest rates all staying low during Labor's term, the more the Libs have focused on attacking its economic management by repeating the Costello line that deficits are always bad and by exaggerating the size of its debt.
Rather than patiently explaining the economic ignorance of this deficit demonising, however, Labor capitulated to it, with Julia Gillard promising faithfully in the 2010 election campaign to have the budget back to surplus by this financial year.
Problem is, the budget has not played ball. Much to the amazement of economists (and the consternation of Treasury's forecasters), the recovery in the economy has not been accompanied by a commensurate recovery in tax collections. Among the many reasons for this, the main one seems to be that our dollar has stayed high even though the prices for our mineral exports have fallen back.
This dawning reality is what forced Wayne Swan to concede just before Christmas that the budget would remain in deficit this financial year. Knowing the weakness on the budget's revenue side is likely to continue indefinitely, he's made no new commitment on when it will be returned to surplus.
But he and Penny Wong keep saying they won't be cutting government spending just to get the budget back to surplus, for fear of this costing jobs. Clearly, they've allowed their membership of the Deficits Are Evil Club to lapse.
For years the Libs have condemned Labor's timid explanations as mere excuses and have been promising to return the budget to surplus as soon as they got back to office. But the reality of the budget's revenue weakness has finally dawned on them, too.
Last Thursday, Abbott declared that "all bets are off" on the question of when a Coalition government would achieve a surplus. He's repeated the warning since. And also on Thursday, shadow treasurer Joe Hockey advised that "we are not going to go down the path of austerity simply to bring the budget back to surplus because it would end up being a temporary surplus".
So though we can expect to hear a lot more about Labor's alleged bad budgeting, we'll be hearing nothing more about achieving surplus ASAP. For both sides it's now a mere "aspirational objective".
I fear, however, we're swinging from one extreme to the other, from falsely claiming budget deficits are always evil to complacently accepting them long after it's become prudent to eliminate them and start repaying debt.
To say deficits aren't always evil is not to say they're always OK. So be warned: when budget surpluses fall out of fashion with the politicians, it won't be long before they're back in favour with economists - and commentators such as me.
