The writing major is appealing. I have an ABJ degree (Bachelor of Arts in Journalism), with a major in magazines (roughly like having a writing major) and took courses in both nonfiction and fiction writing. However, as I went through the program, I discovered that writing jobs are few and far beween. (I ended up getting a Ph.D. in sociology and becoming a professor.)
To my knowledge, most magazine journalism majors end up, after graduation, doing the same thing as newpaper journalism majors - working for a small newspaper.
The articles written in most magazines? They are largely written by freelancers. Most do not make enough money freelancing to use it as a sole source of income.
My suggestion, for what it is worth, is to speak with professors in the area you want to study and ask them about current job openings. Then find out from the university's career placement office what jobs recent graduates have secured.
Cheers,
Mark
