Don’t expect to see a lot of newspapers and Web sites with this headline: “Big Government Bailout Worked.” But it would be entirely accurate.

The actual headlines make the point. “Demand for fuel-efficient cars helps GM to $3.2 billion profit,” declared The Post. “GM Reports Earnings Tripled in First Quarter, as Revenue Jumped 15%,” reported the New York Times.

Far too little attention has been paid to the success of the government’s rescue of the Detroit-based auto companies, and almost no attention has been paid to how completely and utterly wrong bailout opponents were when they insisted it was doomed to failure.

“Having the federal government involved in every aspect of the private sector is very dangerous,” Rep. Dan Burton (R-Ind.) told Fox News in December 2008. “In the long term it could cause us to become a quasi-socialist country.” I don’t see any evidence that we have become a “quasi-socialist country,” just big profits.

Rep. Lamar Smith (R-Tex.) called the bailout “the leading edge of the Obama administration’s war on capitalism,” while other members of Congress derided the president’s auto industry task force. “Of course we know that nobody on the task force has any experience in the auto business, and we heard at the hearing many of them don’t even own cars,” declared Rep. Louie Gohmert (R-Tex.) after a hearing on the bailout in May 2009. “And they’re dictating the auto industry for our future? What’s wrong with this picture?”

What’s wrong, sorry to say, is that you won’t see a news conference where the bailout’s foes candidly acknowledge how mistaken they were.

The lack of accountability is stunning but not surprising. It reflects a deep bias in the way our political debate is carried out. The unexamined assumption of so much political reporting is that attacks on government’s capacity to do anything right make intuitive sense because “everybody knows” that government is basically inefficient and incompetent, especially when compared with the private sector.

Government failure gets a lot of coverage. That’s useful because government should be held accountable for its mistakes. What’s not okay is that we hear very little when government acts competently and even creatively. For if mistakes teach lessons, successes teach lessons, too.

In the case of the car industry, allowing the market to operate without any intervention by government would have wiped out a large part of the business that is based in Midwestern states. This irreversible decision would have damaged the economy, many communities and tens of thousands of families.

And contrary to critics’ predictions, government officials were quite capable of working with the market to restructure the industry. Government didn’t overturn capitalism. It tempered the market at a moment when its “natural” forces were pushing toward catastrophe. Government had the resources to buy the industry time.

What’s heartening is that average voters understand that broad assaults on government provide better guidance for the production of sound bites than for the creation of sensible public policy. That’s why House Republicans are backpedaling like crazy on their plans to privatize Medicare — even as they pretend not to.

Conservatives really believed that voters mistrusted government so much that they’d welcome a chance to scrap Big Government Medicare and have the opportunity to purchase policies in the wondrous health insurance marketplace. Don’t people assume that anything is better than government?

But there were deep potholes on the road to a market utopia. Put aside that the Republican budget wouldn’t provide enough money in the long term for the elderly to afford decent private coverage. The truth is that most consumers don’t have great confidence in the private insurance companies, with which they have rather a lot of experience.

When it comes to guaranteeing their access to health care in old age, most citizens trust government more than they trust the marketplace. This doesn’t mean they think Medicare is without flaws. What they do know is that Medicare does not cut people off in mid-illness and that its coverage is affordable because government subsidizes it.

It’s axiomatic that government isn’t perfect and that we’re better off having a large private sector. It ought to be axiomatic that the private market isn’t perfect, either, and that we need government to step in when the market fails. The success of the auto bailout and the failure of the Republicans’ anti-Medicare campaign both teach the same lesson: The era of anti-government extremism is ending.
