Latin America is a continent of underdeveloped countries, by any criteria. A terminological discussion as to whether they are underdeveloped or developing would be quite irrelevant. The fact is that Latin America has an explosive population expansion, a low educational level, low health standards, a low life expectancy, poor work conditions, a small middle class, problems of national integration, a low level of industrialization, low per capita income and GNP, low development of agricultural and fishing resources, low consumption of mechanical and industrial energy and excessive expansion of the commercial sector, not to mention the character of the political situation and its consequences. In these countries the majority of the people live in very poor conditions, under a traditional social structure of a few ‘haves’ and a large number of ‘have-nots’.
