It’s not a blanket “get a masters and you leapfrog everyone else into a job” .
You're absolutely right, it isn't, I totally agree. But nor is it true to say that work experience and/or professional qualifications are de facto better – in some fields they are, in some fields they aren't.
I can assert that a lot of scientific research positions are likely to require a Masters, whether field or lab based. This does not necessarily mean staying in academia, it would also encompass jobs with medical charities, NGOs, in government labs and at private pharmaceutical companies. You might get a job at such places, but sooner or later you will hit a glass ceiling above which you will need further degrees if you wish to progress. I don't know if other posters consider that 'lots of jobs' or not, to me it does, but I guess opinions on that may vary.
DD2 has a first-class Masters from a university ranked above everywhere in the UK except Oxford for her particular field of study. Having looked into it closely, she has assessed that this is the minimum she needs for her chosen career.
Back to the OP and as I have already said a career in publishing is not going to require a Masters. Indeed, newspapers used to prefer people who didn't have degrees at all, they would rather train them on the job, though that has changed now as there are lots more degrees in journalism, marketing, communications etc than there used to be.
