An interesting and thought provoking post. My husband teaches science in a small religious school where humanities (and arts) are neglected in favour of science and business. I have had many discussion with him, (having a background in a humanities/science degree myself) that I feel more balance is needed. He agrees but says the culture of the school and parents meant that offering these subjects was not viable, which I felt was a bit sad. We need a balance population with interests and knowledge in a range of subjects and I think research and independent thoughts should be encouraged throughout this range. You’re not a failed PhD student, the fact you started it is an achievement in itself, and it sounds like the system failed you.
