Because we're not radically left-wing enough for your taste?
Dude, what's your malfunction? It's pretty damned clear to everyone that American journalism, never as reputable as it presented itself, is at an all time low.
The right thinks the media is liberal and the far-left (Counterpunch and DU) thinks the media is conservative. They can't both be right.
They're both largely mistaken. Studies of journalists and people in the media field suggest that most are socially liberal but economically conservative. ie, they're all for things like civil rights, as long as it doesn't cost anything. They're actually for balanced budgets, low taxes, fiscal responsibility, reducing welfare, cutting back on social spending, etc.
Of course, this sort of 'liberalism' leads to undue emphasis on boutique issues with no real economic consequences - gay marriage. This means that the lunatic right seizes on these airy, weightless, abstract causes and flogs media as being left wingers.
Things like equal pay for equal work, affirmative action, health care or social services either get ignored or get the bums rush as being too expensive for economic conservatives/social liberals. People with a brain notice this inherent contradiction, and flog the media as being hypocrites or merely conservatives in 'independent' clothing.
However, when you move from the bulk of journalists and media people, and look at the actual management structures and management personnel in place, suddenly, the media breaks steadily to the right in every respect and becomes relentlessly strident.
Even there however, they're not right wing enough to satisfy the lunatic right. Only guys like Glenn Beck and Rush Limbaugh manage to cater to that pack of morons, and they do so only by foaming at the mouth.
Rather, people involved in ownership or management of media, ie, the ones who actually make the decisions, about what stories get done, who or what gets covered, what is or isn't news tend to be 'business right wing.' What's good for the corporate interests is good for the media.
Honestly, do you think the media did a bang up job on Iraq? How about this steaming pile of integrity - a major media outlet discovers that the President of the United States has undertaken an illegal spying program on American citizens.... and then sits on it for a year, because they wouldn't want to influence an election.
This isn't to say that the American media is completely incompetent or worthless. If some teenage white girl goes missing, well, let's just say that the coverage is extraordinarily thorough. And when Paris Hilton pees in a taxicab... we all get to hear about it.
As for the rest? Well, there's a reason America's newspapers are dying. It's called self inflicted injuries.
