Maybe photography and entrepreneurism as a joint major - mix it with a business degree that would be helpful for other endeavors, as well as creating her own business. This will be a tricky search for schools, b/c both majors are not as common.
As a side note, one of our office bldgs has a tenant that is a photography company - they have a popular app and create digital plugins for professional photographers. The founder is a former wedding and bar mitzvah photographer who always pursued his passion, and they’ve now raised over $70MM in B round VC money (for those of you outside the Bay Area or tech world, this is a lot of early stage money). For smart people, you can figure out a way to pursue your passions and still make a $ or two. You just need to have the will and you can find the way. But it will never be as comfortable or “easy” as pursuing a more traditional discipline with strong job prospects.
BTW, your daughter’s view of your husband’s engineering career is warped and she should be corrected on that - no job is secure today, in virtually any industry. Especially those that pay well or have strong upside - not only are you an easy target to cut costs, but there is always someone else willing to take your spot.
