Edward S. Herman book Manufacturing Consent: The Political Economy of the Mass Media
The evidence of worth may be read from the extent and character of attention and indignation. […] the U.S. media’s practical definitions of worth are political in the extreme and fit well the expectations of a propaganda model. While this differential treatment occurs on a large scale, the media, intellectuals, and public are able to remain unconscious of this fact and maintain a high moral and self-righteous tone. This is evidence of an extremely effective propaganda system. […] The worth of a victim Popieluszko [Polish priest] is valued at somewhere between 137 and 179 times that of a victim in the U.S. client states, or, looking at the matter in reverse, a priest murdered in Latin America is worth less than a hundredth of a priest murdered in Poland.
