Although for many political leaders, journalists or academics talking about the working class today is an anachronism and is outdated, this book aims to claim the social validity and political importance of a class that has in its hands the possibility of transformation social, although not always aware of it. With the self-confidence and sarcasm of a rapper who was eight years a blue monkey welder and the wisdom acquired by a young woman from the working-class neighborhood who even asked for loans to study "above her means" abroad, the radiography is shown of the working class in our country, the transformations it has experienced in the economic field and its relationship with culture: from its denial in the cinema and its invisibility in advertising, to its lynching and caricaturing in television. Its minority presence in the University of the masses, its stormy relationship with the academy and, not least, its close and sometimes distant synergy with the traditional leftist parties. Without paternalism but also without concessions, as only the class pride of who was born in the working class (and did not visit it as a tourist) is able to achieve.
