I make $48k. My BS is in engineering - I could triple my pay in the private sector.
Bennies are not as good as I had working for a major chemical company; nor are they as good as dear hubby receives from a major oil company.
Since I teach college-level mathematics to high schoolers, I'd say an advanced degree (at my own expense) is a benefit to my students. Dear Hubby's employer paid for his MBA.
