From my own experiences, I have to say yes and no. A lot of people might say that at first, but when they try their hand at it, are shocked at how terrible it is. Then, there are others who are encouraged by people who know nothing about writing, who then think that they are really spectacular at it. This is weird, because math is much less subjective and in my view, "easier" to teach, as the edges are much more clearly cut. I get what you're saying, but I have to disagree with the words "good" and "great". In my view, there are very, very few truly great writers. For example, Mark Twain was great, whereas J.K. Rowling is good (not saying I like her stuff). I think if you're good, then you should be paid too. Especially because for a job, most of the time greatness is unnecessary, merely being good enough. Which brings me to my point. Writing should be considered a job. And it's not. Unless one is a full-time novelist (of which there are few) or a journalist (of which, there are also few, though there are a great many hacks out there).I think the biggest issue is that people assume that writing is a skill that "anyone can do,"
as opposed to something like math, which is considered a more narrow focus that you need an "expert" for.
Like anything else, there is a difference between good and great. And like anything else, if you're great, you should get paid to do it.
