And why not?
What, after all, does the study of "journalism" really train one to do?
What useful thing, I mean?
Nothing. You’ve put your finger directly on the reason for their ultimate demise.
Take aviation disasters or incidents as an example of where the press usually gets so much wrong. What value does the ‘journalist’ bring to the picture? Nothing, IMO.
I can flip out a question to the ‘net and have hundreds of people who are overwhelmingly more qualified than a ‘journalist’ give comments, perform analysis and report on any aviation incident. At the mere askance of a question, we can have INFORMED, EXPERT analysis from USAF vets, actual pilots of aircraft large and small, civilian and military, of all levels and hours of experience and ratings. Sure, their grammar might not be as polished, and they might not follow all the pretty rules of the CJR. But they’ll have the facts correct from the get-go; ie, they’ll render substance over style.
All of these men and women will be more qualified to write a factual story than anyone with a ‘journalism’ degree.
