You seem to have an agenda to try and prove that journalism as a vocation is fundamentally broken, and this leads you to make hyperbolic statements and clutch at strawmen.
Take a look a little deeper and you'll see that journalism is a profession with ethical standards and is actually pretty robust and, perhaps, even honourable - it's the funding and business models that are the issue, but the actual practice is quite sound.
I am not observing any evidence of such processes existing. In fact, I am observing exactly the opposite - people freely moving between being political operatives and newspeople, political parties coordinating propaganda campaigns with friendly news anchors, known news personalities being openly hyper-partisan and not being challenged on it in their organization, independent thinking people being forced out (e.g. Sharyl Attkisson) and so on. I don't see any self-criticism going on.

Journalism as a vocation is not broken. Journalists as a practitioners of the profession as it is practiced now are. Yes, there exist professional journalists, who do what they are supposed to do, honestly. Many of them. But now they are going against the stream, and working against the odds. And one has to be blind to not see that situation is getting worse, the trust in media reporting is dropping and the quality of news content coming from major outlets is terrible. You can call it "broken" or you can call it "temporary difficulties which do not influence averages which are still excellent" but its in plain view for everybody to see. And it's not my agenda - there are a lot of people around recognizing the same. Otherwise we wouldn't need special startups to do what journalists were supposed to do.
> you'll see that journalism is a profession with ethical standards
Ideally, yes. However, I don't see these standards being really enforced or even seriously heeded to. Very rarely I see any analysis done on bad reporting, and only in a case the organization was externally caught and called out on it. Maybe you're right and I am focusing on the visible outliers, but it seems to be that there are too many "outliers"...
> We've already solved this problem: Professionalism
You say it as if it explains something. But it doesn't - what's "professionalism"? There are a lot of people that are literally paid millions to deliver news, and if you're interested in news (and not, for example, in making fun of the person you disagree with or reinforcing your preconceived notions about people disagreeing with you being evil and stupid) they are doing a spectacularly crappy job. Are they "professionals"? And if not, where does one gets them? Are people that fake scientific data "professionals" (happens all the time)? Are people that make grand political claims based on shoddy research or no research at all "professionals" or not? Where does one get that "quality culture" which would eliminate those common occurrences?
