Don't despair, the job outlook for this type of major is not necessarily as grim as folks would have you believe. Truth be told, while it can be difficult to get one's foot in the door, it really is about work and working hard to gain the skills and knowledge you need no matter what the major.
So, if your daughter takes her education seriously and truly works on making her core foundation as solid as possible, she will prepare herself for opportunities unknown. It is what any university education should do. Despite what has been said about universities should be "like a business and give the consumer what they want: a degree," I am a firm believer in personal responsibility and that what students should be consuming is as much breadth and depth of information as they can possibly hold and learn how to build a framework for adapting all of it toward their future. (Being adaptable about going to where the jobs are is part of the equation.)
If your daughter takes as many science/math or other STEM electives as she can, she may discover she has a knack for technical writing. Science and the applied fields always need good writers, trust me. It is one way to converge her interest with her new passion. Also, by having a solid foundation, if she discovers that one or more of these fields is something she truly enjoys doing, she will find that the work she puts in on the path to a solid career seems more satisfying. There are even people who study the history of science. How cool is that?!
Public relations has a large range, but if you are very adept and willing to work hard, it can be lucrative.
Like Fishing Fools related, there are also careers in education and the like.
Finally, and I am going to step up on my soapbox for a moment, attending college is what you make of it. Some folks say that the classes they took "didn't prepare them for the real world." I say if that is the case, then they should look in the mirror. If they slid their way into a degree, then they missed a golden opportunity to prepare "for the real world." Take the coursework seriously even if others around you don't. Use that opportunity to expand your knowledge so that whatever life throws you, you may discover a new path instead of being lost in the weeds. With a solid foundation and your guidance (from afar) she will be on her way to a bright future.
Good luck to her!
Technical writers median salary is around $70K, public relations is anywhere from less than $64K to greater than $100K but it depends on the field and can be volatile (think politics). The job outlook for journalism has not been great. The world needs investigative reporting. It is important to have transparency worldwide but it is definitely a career path undergoing upheaval for a variety of reasons. I'm sure I'm not telling you anything you didn't already know. On the bright side, however, a hs classmate of one of my children was recently on a team of reporters that were awarded a Pulitzer. Some of life's rewards are not monetary...
