It’s one of the most frustrating aspects of the Villager mentality. Liberals are misrepresented terribly in the media and it’s glacially slow in changing. I’m hopeful that it is happening, but the social and professional structure of organizations are very difficult to change without a consciousness of the problems. And I don’t see much media consciousness of this problem. And to the extent they understand it, they are misapplying the lessons.

She’s complaining that the Washington Post isn’t cognizant of/responsive to the “problem” of true-blue actual liberals being underrepresented in the mainstream media. Sigh.
Look, I know she reads Jonathan Schwarz at A Tiny Revolution more or less regularly, because she links to him often enough. Somehow, though, she manages to miss the posts where he explains these things so clearly:
The Washington Post is a corporation, required by law to make as much money as possible. In order to make as much money as possible, businesses cater to their customers. The main customers of the Washington Post are their advertisers, who are mostly other big corporations. Big corporations, for obvious reasons, like it when people are misled about economic policy, the Great Depression, FDR, etc.
That’s really all there is to it.
It’s as if someone took a look at the fall lineup for network TV and complained that there were no shows devoted to promoting an ethic of voluntary simplicity. Surely you wouldn’t be shocked to find that corporate culture doesn’t have any interest in undermining its entire raison d’être. Whence, then, this notion that corporate media exists purely to inform the citizenry in the most objective, comprehensive way possible?
