When it comes to America's AAA debt rating, we have to ask whether we would be better off without it.

That notion is pure heresy, and Treasury Secretary Timothy Geithner was quick this weekend to try and dispel any thought that the US would ever be in for a downgrade.

"That will never happen to this country," Geithner said during an interview with ABC News. The remark came after Moody's Investors Service last week said the pristine US rating will come under pressure unless something is done about mounting deficits.

Geithner shouldn't have fought Moody's report. He should have embraced it. What better way to impress upon Congress that the US is very much in crisis and needs to face up to its problems.

Fears

That reality has yet to set in on Capitol Hill. Two weeks ago, for example, the Senate shot down a proposal to create a deficit-reduction commission. The measure failed because the Left worries such a committee will cut spending, while the Right is afraid it will call for tax hikes.

So no spending cuts or tax hikes, which is what we need just deficits as far as the eye can see. Let's break out the fiddles already and watch Rome burn.

This is why concerns over the so-called PIGS (Portugal, Ireland, Greece and Spain) or those on the geographic and economic periphery of the European Union are really a sideshow. The real danger to markets lies with the DOLTS, or Dangerously Over-Leveraged Triple-A Superpowers.

That club currently consists of the US.

So far, membership has allowed the US and its elected representatives to pretend urgent action isn't needed. After all, DOLTS have the world's reserve currency and nukes.

This supposedly means we can spend our way out of debt because creditors like China will forever lend us money. Failing that, we can just print more dollars.

Yet even these benefits can't change the fact that the US is on an unsustainable course with deficits rising, the national debt soaring, and Social Security and Medicare preparing to go bust. At 10 per cent of gross domestic product, the $1.6 trillion budget deficit for 2010 forecast by the Obama administration ranks as the highest such ratio since the Second World War.

The administration predicts that this ratio will fall to about 4 per cent by 2015. For that to happen, though, the economic recovery mustn't sputter.

US weakening

Debt, meanwhile, is set to climb to 77 per cent of gross domestic product by 2019, according to Moody's, while "debt affordability would be weakened by higher interest costs in the next several years."

That compares with government expectations at the end of 2008 of a future debt-to-GDP ratio of about 40 per cent by the end of this decade.

No wonder investors like Marc Faber, who publishes the Gloom, Boom and Doom report, say the US would carry a below- investment grade, or junk, rating if the country were a company.

And starting in 2020, things will get even worse. "It is worth noting that after 2019 is when the most serious pressures resulting from Social Security, Medicare, and Medicaid will develop, so that failure to rein in the deficits would make it even more difficult to deal with such pressures," Moody's said in a credit opinion last week.

State and local governments are also in crisis, and, like their federal counterparts, are unwilling to face the harsh reality confronting them.

The mire facing California, for example, makes Greece's woes look somewhat manageable. California, staring at a $20 billion budget gap over the next 17 months, accounts for about 13 per cent of the US economy. Greece accounts for just 3 per cent of the economy of countries that use the euro.

Things are so bad in Nevada, meanwhile, that the state could lay off every worker paid from its general fund and it would still be $300 million in the red, according to state Assembly Speaker Barbara Buckley.

Given all this, Geithner should be using Moody's AAA talk as a cudgel to beat some reality into congressional heads. So far, though, President Barack Obama has preferred to kowtow to House Speaker Nancy Pelosi and Senate Majority Leader Harry Reid, rather than lead them.

So while the threat of a downgrade might be unsettling, allowing the country to continue along its present course is far worse.
