Alexander Field,  an economic historian, believes  that despite the Great Depression, the movers and shakers of the 20th Century were last seen between the years 1929 and 1941 and resulted in the highest rate of productivity growth throughout the  Century.

His hypothesis follows that the Depression years produced advances that replenished and expanded the larder of unexploited, or only partially exploited, techniques as businesses and Government implemented, or adopted, a wide range of new technologies and practices.

It will be interesting watching this decade come to a close over the coming months whilst being mindful of the considerations and components that make up such hypothesis.
