I still remember the super nice guy I worked with at HP/Owens Corning who had a masters degree in Ancient Greek History. I asked him what he can do with that degree and he said very sadly, "Teach". He wasn't happy about it. He followed his interests and ended up with something completely worthless. There he was working a 3rd shift computer operator's job with a guy who was just starting his career after the military.
Not saying we don't need experts on ancient Greece, but the job opportunities are scarce.
