If only those disciplines would not be shifting. Being in my mid 40s now I have seen shifts to and from mechanical/electrical engineering, physics, biology, chemistry, computer science, business or law degrees and many more.

Actually when I graduated from high school the safest and easiest path to employment that was recommended to us was to study a humanity and become a teacher (teachers here - Central Europe - are much better paid than in the US) or get a business degree and work for a bank or insurance company. Both of these paths seem ridiculously risky now (or at least last time I checked).

As a conclusion I would argue that there is no such thing as a "free ticket to a successful career". Chances are high that at one point or another there will be a surplus of people in everyones profession and almost everyone will experience unemployment or need to shift careers.
