I studied history with no plan for what to do in the real world. Now I run my own consulting business and am planning on bootstrapping it into a software business.
Look: You can get a job by making choices that HR departments like or you can go and carve out an economic niche for yourself. Your degree isn't important in the latter so much as your ability to think critically. Perhaps humanities degrees (including a philosophy degree) really shine there.
I have a degree in Computer Science and Philosophy[1] (graduated in 2010) and I think the second part of that degree has helped me more in interviews and in life than the first part by a wide margin.
It put me in a very interesting position when applying and interviewing because (apparently) nobody ever sees that degree or combination and they always ask about it. I was able to wax eloquent about how I love writing, debating and clear communication. How I have a firmer grasp of logic because of my (more technical) philosophy courses and how it has allowed me to relate better and communicate more effectively.
Good communication and writing writing skills, as well as a willingness to write are I think (and many have seemed to agree) in short supply in the computing fields and I think that almost any humanities degree would add an enormous amount of value to a person, provided they can do the computing parts of their job as well!
[1] This means that I completed all of the requirements to get either degree, but didn't have the sheer credit hours to literally get two pieces of paper. My diploma could just as easily read "Philosophy and Computer Science" instead.
