Even STEM and healthcare is a mixed bag. A biology B.S. is basically useless without further education (the running joke is that the janitors in biology labs are people with bachelor's degrees). Not really sure what "pure" chemistry or physics degrees would be able get employment-wise, either (chem engineering being the exception and one of the few super-lucrative degrees where only a bachelor's is needed, but in my experience chem eng and chemistry are two different degrees).
Nursing, yes, you'll always have a job if you work clinical nursing, but it's a high-stress job that is figuratively and literally shitty. You can enter administration like myself, but once you make the decision to go administration track, you are railroaded into non-clinical for the rest of your career and open yourself up to more job insecurity than a clinical nurse. Nurse practitioner is a good job on paper, but it's a highly saturated field due to diploma mills (unless you want to move to Bumfuck, Nowhere). My sister is a speech pathologist, which was one of the "hot" degrees 5-10 years back, and all she's been able to find are part-time positions despite her getting out of her master's program with a 3.9 GPA.
