By any normal standard, economic policy since the onset of the financial crisis has been a dismal failure. It’s true that we avoided a full replay of the Great Depression. But employment has taken more than six years to claw its way back to pre-crisis levels — years when we should have been adding millions of jobs just to keep up with a rising population. Long-term unemployment is still almost three times as high as it was in 2007; young people, often burdened by college debt, face a highly uncertain future.

Now Timothy Geithner, who was Treasury secretary for four of those six years, has published a book, “Stress Test,” about his experiences. And basically, he thinks he did a heckuva job.

He’s not unique in his self-approbation. Policy makers in Europe, where employment has barely recovered at all and a number of countries are in fact experiencing Depression-level distress, have even less to boast about. Yet they too are patting themselves on the back.

How can people feel good about track records that are objectively so bad? Partly it’s the normal human tendency to make excuses, to argue that you did the best you could under the circumstances. And Mr. Geithner can indeed blame much though not all of what went wrong on scorched-earth Republican obstructionism.
