I respect various professions in inverse relation to how much they mythologize themselves. Plenty of people think their jobs are important, but only certain ones seem to have constructed a whole romantic vision around this importance. Journalists are definitely guilty of this.
I should elaborate on this, but I've got better things to do, like go make some enchiladas. I'll just say this: I bet if if you ask a thousand journalists what they think the five best movies are a huge percentage of them will mention All the President's Men.
