>>I understand a student wanting a Master's, but the little extra knowledge gained with a Phd seems pointless? I think you might be a misinformed. A Ph.D. does not give you "a little extra knowledge" over a Master's. It allows you to deeply specialize in a small part of a given field. By the time you get your Ph.D., you're one of the world's foremost experts on that narrow topic. The value of that might be arguable based on what you studied (e.g. linguistic history of languages in Tanzania might be too obscure), but a Ph.D. is far more knowledgeable than someone with Master's. The primary difference between a Master's and a Ph.D. is that the former is industry-oriented whereas the latter is research-oriented. That the latter is a continuation of the former is a a common misconception.
