What do people with bachelor's degrees in humanities actually end up doing? If someone majors in political science or international relations or history, what do they end up actually doing as a career?

I've found numerous sites that give the obvious answers what they can do, but to date no site that says what they actual do.

It's all fine and dandy thinking that an International Studies degree will prepare you for a career as a diplomat, but if 95% of graduates end up selling life insurance, or filling out form 2773A-11 for some bureaucracy, I may want to make a different set of choices.
The reason certain courses (engineering, law, medicine) are referred to as 'professional courses' is that they prepare one  for a particular profession, and that is the primary goal of the course.
In any other course, it is a good idea to assume that you are being taught various skills, but not necessarily being prepared for a career. To expect a career out of a humanities degree may therefore be misguided.  Best to look at it as a stepping stone that could lead you in a multitude of directions.
