There is a saying among economists that goes as follows: "throughout history there have only been four kinds of economies in the world: advanced, developing, Japan, and Argentina". Around 1900 Argentina was among the top five countries in the world in terms of income per capita. Today, Argentina is close to the average country in the world, with income per capita at only 40% of the 12 core EU countries! What has happened? Why this sudden reversal of fortune?
