Of course journalists will never consider that their enterprise would require reform. They are used to being the question makers and opinion formers.
I suspect if we got rid of them all the world would be no worse off. People would communicate to each other as before and nothing of value would be lost. Perhaps less coordination of mind-share is what we need. Does anybody seriously believe our political systems improved with the availability of 24 hour news? Perhaps our political leaders should not be available on camera at all. I don't see what the argument is that more journalism and televisual display somehow made politics better. It made it more theatrical and less practical. How was that supposed to improve governance?
tldr; They don't like it up 'em.
