This paper provides an analysis of the organizational model of the political and the civil societies which became prevalent in Western Europe after the Second World War: the Welfare State. It also provides a discussion on the reasons why this model of organization has never been effectively implemented in any Latin American country. To this end, firstly, the text highlights the many and most important characteristics of the Welfare State, with attention to the peculiarities it assumes in specific European countries. Secondly, based on these comparative elements, a typological synthesis of the Welfare States is drawn, considering the range from the most sophisticated examples to those which only meet the minimum relevant criteria of this model of State and social organization. Finally, the reality of Latin American countries is analyzed and it is indicated to what extent they have (or have not) structured something that could be effectively considered a Welfare State. In this framework, it is concluded that, although there are a few Latin American countries showing progress in terms of achieving these characteristics in comparison with the great majority of countries in the region, the obstacles and challenges for the full structuring of a real Welfare State in this region of the globe are still persistent.
