Sounds like a relative working on a nurse practitioner degree. $50K cost for a job that will pay less than what he is making now. There will be some positive trade offs in job safety and family life, but the economics do not make sense.
Out of curiosity I googled the salary for a nurse practitioner. According to salary.com it’s about 84k.
So maybe it will work out okay. It’s not necessarily safer unless he works for a bomb squad or as a Baltimore policeman. Many nurses get assaulted by out of control patients.
