> they literally spend all day every day absorbing, summarising and writing about context as their full time job.

I have no idea what "absorbing" means and how it's different from any random dude spending his day sitting on a couch glued to CNN/MSNBC screen. But the fact that they are professional writers doesn't give them any special quality in the insightfulness of their writings - you can be a professional writer and a complete doofus, to which we have an ample number of examples.

> They are trained formally at assessing, evaluating and questioning facts.

No they are not. Maybe they used to, somewhere in ancient times, but there's no slightest trace of any of it in most of the content produced by major press outlets. If they can do it - which I very much doubt - they certainly aren't bothering to.

> You can criticise the end result

By their fruits you will know them. The end result is the only criteria worth considering.

> I can't see how it's reasonable to say they aren't far better positioned to have an informed opinion

Some of them - with access to sources unavailable to regular people - may be better position to form an informed opinion, if they wanted to. But as soon as that information has been published, they do not have that better position anymore. And in addition to that, what is frequently happening is that they do not just publish the information available to them - instead they distort it and modify it to fit their pre-conceived opinion, and publish that, in hope that the public doesn't know any better (it usually does). If there is any truth to separation of news and opinion sections that we were told so much about it, then by that mere fact the opinion writers don't have any special informational insights - only the news people, working with confidential sources, might.

> the average reader who gets up in the morning with no training

What is that mythical "training"? I see no evidence of any relevant "training" in anything I read in the press. Most of them know how to handle basic grammar and write somewhat coherent text, but any person with basic education can. Beyond that, I don't see any special "training" there. And certainly there is an ample number of people who undergo much more rigorous training about how to handle facts, e.g. when studying hard sciences. Most press opinion writers do not undergo anything like that.

> tries to understand a slew of facts dumped on them without context.

What is that mythical "context" not available to regular people and where does it come from? Is there some secret "context sources" that are only opening if you work for WaPo? What is stored in those "context" treasuries?

I think their existence is a complete fiction. There's just a bunch of people who are getting paid for publishing their opinions because they have a degree saying "journalism" on it or just because they applied to the job and got hired, but they don't have any special insight or "context". I mean, some of them might be just good at thinking and making conclusions (they usually don't survive in the press long) but that would be just random luck. Given the selection pressure, I'd expect lower chance to find such people among professional press than just in a random selection of people with the same class and education level.
