Most of us do need to work for a living. Researching for the sake of research, and learning purely because one is interested in the subject is nice and all, but it is a luxury few can afford. I think it is beneficial for everyone that the money angle for PhD is openly discussed and made public. This way, the correct audience (those who don't need to work for a living, i.e. born rich) might be attracted instead of burning out middle/lower class youth with dreams. ...Or steps can be taken to change PhD programs. Which does not seem likely.
