Also, I don't know much about philosophy (and I suspect this is far less applicable for philosophy), but in science and engineering often mastery and innovation in a field requires an extremely narrow focus that, in turn, requires a significant investment in time and resources. This includes transmission of specialist knowledge to graduate students and postdocs, grant writing, paper publishing, acquisition of equipment or access to equipment. So I don't really think it's entirely fair to chalk up lack of interdisciplinary interest and/or innovative methodology predominantly to a system that weeds out people not willing to think the way it wants them to. (Not saying that tenure doesn't have its own problems...)
As a two grad-student couple, we have mutual academic envy. I envy that she finds it easy to memorize large sums of material and pander to the system. She envies that I find it easy to acquire an intuition for the material I really care about. I envy that she's "saving the world" as an ecologist. She envies that I can make a good living out of my field.
Arguing with them on that point proved useless in the past, but now that I get interesting internships while they don't, I believe they are somehow waking up.
At least, focusing on being a 'good student' is not the worst strategy out there. If one day you come to be aware of it, it's not an irrecuperable situation.
