James Galbraith:

In short, if we are in a true collapse of finance, our models will not serve. It is then appropriate to reach back, past the postwar years, to the experience of the Great Depression. And this can only be done by qualitative and historical analysis. Our modern numerical models just don't capture the key feature of that crisis -- which is, precisely, the collapse of the financial system. If the banking system is crippled, then to be effective the public sector must do much, much more. How much more? By how much can spending be raised in a real depression? And does this remedy work? Recent months have seen much debate over the economic effects of the New Deal, and much repetition of the commonplace that the effort was too small to end the Great Depression, something achieved, it is said, only by World War II. A new paper by the economist Marshall Auerback has usefully corrected this record. Auerback plainly illustrates by how much Roosevelt's ambition exceeded anything yet seen in this crisis:

[Roosevelt's] government hired about 60 per cent of the unemployed in public works and conservation projects that planted a billion trees, saved the whooping crane, modernized rural America, and built such diverse projects as the Cathedral of Learning in Pittsburgh, the Montana state capitol, much of the Chicago lakefront, New York's Lincoln Tunnel and Triborough Bridge complex, the Tennessee Valley Authority and the aircraft carriers Enterprise and Yorktown. It also built or renovated 2,500 hospitals, 45,000 schools, 13,000 parks and playgrounds, 7,800 bridges, 700,000 miles of roads, and a thousand airfields. And it employed 50,000 teachers, rebuilt the country's entire rural school system, and hired 3,000 writers, musicians, sculptors and painters, including Willem de Kooning and Jackson Pollock.

In other words, Roosevelt employed Americans on a vast scale, bringing the unemployment rates down to levels that were tolerable, even before the war -- from 25 percent in 1933 to below 10 percent in 1936, if you count those employed by the government as employed, which they surely were. In 1937, Roosevelt tried to balance the budget, the economy relapsed again, and in 1938 the New Deal was relaunched. This again brought unemployment down to about 10 percent, still before the war.

The New Deal rebuilt America physically, providing a foundation (the TVA's power plants, for example) from which the mobilization of World War II could be launched. But it also saved the country politically and morally, providing jobs, hope, and confidence that in the end democracy was worth preserving. There were many, in the 1930s, who did not think so.
