I think that you make a good point, but on the other hand it seems like the number of degrees which are "safe bets" are decreasing. For example, my understanding is that a business degree is much less likely to get you into the middle class than it used to. Similarly, I think there was a time when BS degrees in the sciences were enough to get decently paid technician jobs. Now it seems like engineering and medicine are the only degrees with a guaranteed return.
