Nothing evokes the misery of mass unemployment more than the photographs of the Depression. You can see it in the drawn faces of the men, in their shabby clothes, in their eyes. Their despair spawned political extremism that left a stain on society; but it also taught subsequent generations that public policy has a vital part in alleviating the suffering of those who cannot get work. Thanks to welfare schemes and unemployment benefits, many of which have their origins in those dark days, joblessness no longer plunges people into destitution, at least in the developed world.
Not even the gloomiest predict that today’s slump will approach the severity of the Depression, which shrank America’s economy by more than a quarter, and put a quarter of the working-age population out of a job. But with the world in its deepest recession since the 1930s and global trade shrinking at its fastest pace in 80 years, the misery of mass unemployment looms nonetheless, and raises the big question posed in the Depression: what should governments do?
