As it has become evident that the financial crisis is comparable, in important ways, to the early stages of the Great Depression, there has been a lot of debate about the lessons to be learned from the responses to the Depression in the US, most notably the various policies that made up the New Deal. There’s a lot to be learned there, but it’s also important to remember that the Depression, in the US and elsewhere, continued throughout the 1930s before being brought to an abrupt end by the outbreak of World War II.[1]
Not only did the slump end when the war began, it did not return when the war ended – a huge difference from previous major wars.[2] Instead the three decades beginning in 1940 were a period of unparalleled prosperity for developed countries, with economic growth higher and unemployment lower than at any time before or since.
What lessons can we learn from this experience?
