Book excerpt: The author reminds us all of the huge part that British capital, British people and British technology played in transforming Argentina into a modern 20th century economy. He also analyses the reasons for Argentina's loss of momentum in the post-war world.Much of the history has been forgotten and/or misjudged. That does not make it any less important. In fact, it deserves to be recognised as there are lessons that could be learned from the “golden decade” of development. Those who have an interest in history and development, especially in Argentina, including academics, journalists, historians, and economists will all find this economic and social history of interest.
