There are people that make HONORS with a REAL DEGREE, even with MASTER'S DEGREES that still have trouble finding jobs. Welcome to the real world.
I am not condemning her for not being able to find a job--me and my fiancee were in the same boat for a while. But you don't just go around suing people because things don't go your way. You suck it up, take a deep breath, and move on. Either apply to more jobs, apply to jobs slightly outside of the scope of your degree in order to get an in, consider additional training, or consider moving to an area with more opportunities.
You don't use the legal system as your primary source of income, that's just ridiculous (and stupid). She is going to red flag herself if she keeps it up (if she hasn't already).
