I saw this question:
Why not outsource the research projects to phd students?
It's so badly formulated that it generated a series of comments and answers that have no real connection with each other. It's closed for the moment, but I think beneath the large confusions in which OP is about what is research and what is a PhD, there is an interesting question. Maybe the title could be changed to something like:
- What are the socio-economic reasons for PhD students to receive monetary compensation?
- Why is awarding a PhD title not enough to compensate for a graduate student's work?
While I believe I know very well the answer to these, it might be a question worth exploring. Should we try to improve it, and if yes, how?
