Why is so little of this reported so rarely? In their "propaganda model of media control" Edward Herman and Noam Chomsky identified factors that filter media content.
Media corporations are profit-seeking businesses, owned by very wealthy people or parent companies; they are funded largely by advertisers which are also profit-seeking businesses and want their adverts to appear in a supportive selling environment.
The media is deeply dependent on government and major business firms as sources of information, which tends to promote solidarity between them. Government and large business firms are also best able to pressure the media with threats of withdrawal of advertising, libel suits, and other direct and indirect forms of attack.
All these factors ensure that what we see and read is what powerful interests want us to see and read. Chomsky provides the vital rule of thumb: "The basic principle, rarely violated, is that what conflicts with the requirements of power and privilege does not exist."
