In this episode, we meet Prof. Bradford DeLong to discuss his recent book 'Slouching Towards Utopia: An Economic History of the Twentieth Century.' We cover the rate of technological change prior to the industrial revolution. Before 1500, "the amount of technological change they got in a century, we get in two and a half years"!  We also look at some prerequisites for industrialisation and discuss how the second industrial revolution was the game-changer in terms of long run living standards. After discussing the European turnaround after the Marshall Plan, we finish in the post-war era by looking at "Pacific Rim" development and how it differed from previous modern economic growth episodes.
