"The urgent challenge of winning a total war against so formidable an enemy as Germany, indeed the peril of national defeat, jolted Britain as an industrial society far more effectively than mere peacetime world-market competition, to which she had failed to respond as she should have done according to classical economic ideas. A remarkable technological revolution began in Britain in 1915 and was consummated in 1918 – remarkable not only because of all the deficiencies that had got to be made good, but also because the revolution was accomplished under wartime conditions and at utmost speed. It is also noteworthy that it was masterminded by the government, and that many of the new American-style factories were actually owned and operated by the state."
