I would disagree, and there is one point I would like to clarify. What I'm reflecting is my experience of teaching in the system for twenty years and seeing how things are now as opposed to when I was teaching in the 1980s. I can assure you that as far as I can see, the actual number of people working longer hours is greater now than it was then.
On people changing their programs, I see it as a desirable thing to do. You should be able to change your mind if something suddenly catches your imagination and you feel it's what you really want do. The point I was making is that's becoming more and more difficult for students to do because of the financial penalties for changing your course of study. Taking an extra year or doing additional courses is now so prohibitive that a lot of people feel they can't do that any longer.
