Well like I said before she does pick up a lot of freelance gigs. I'd say that she spends the vast majority of her time working. Often times her job will necessitate a time commitment from her 7 days a week bc they publish content 7 days a week. When she's not doing that she's working on her freelance side projects. It's probably fair to say that if she took a low paying job like stocking shelves in the evening she would probably bring in a little more income than her freelance work but I could see it really jeopardizing her current full time position since she really needs to be "on call" most of the time.
is she a print journalist at a newspaper? if she's good, i'm sure her skills will translate to other fields. to my surprise, i was basically offered a marketing job at an established sportsbook here in vegas not too long ago...on the basis that i am (was) good at twitter. i don't have any marketing background, i'm totally awkward when it comes to selling stuff, and i'm generally not much of a promoter (the website i used to operate was famously non-profity). and yet, someone thought i'd be great for that job and considered me a potential target.
it is true that a journalism degree is (mostly) worthless. but the skills you acquire (that sadly could have been acquired by merely taking a couple of classes) are extremely useful to many fields outside of journalism, and if your soon-to-be wife took a day or two to figure out what those things might be, i'm sure she could elbow her way into a better situation (my definition for "better" in this case is $ based).
if your wife is a decent journalist, then she is likely intuitive, eager to learn, hard working, and good around people. this would qualify her for any number of sales jobs, including those that are commission-based, in addition to customer service jobs with more room for advancement than anything she could be offered in the journalism world.
securing a better-paying FT job and supplementing it with freelance writing work (less strenuous, she chooses her projects) could give her the best of both worlds: she could earn more $ (helps pay debt!) while also allowing her to still be a journalist, which is presumably what she wants to be.
i'm sure i could help identify freelance gigs if it was ever of interest.
