What people mean by value here is murky. Some people are talking about intrinsic value in terms of education. Others, about market value, or overall value. If companies required four years of watching paint dry, would you call that experience valuable? It depends on how we're defining value. Different definitions may be appropriate in different cases. Deciding whether to go is one case (extremely valuable, depending on discipline). Evaluating how useful it is for education is another (in my opinion, it's a pretty terrible value).
