I think western societies are doing themselves a disservice by training people to do just one thing as a career (college "Majors" considered harmful in my view and minors are practically useless). In Neal Stephenson's book "Anathem" all the monks had a fallback profession called an "avocation" which they could do if they failed out of their primary study. And they trained for both when they were young. We'd be much better off as a society right now if we had invested in that sort of approach for the last few decades. Mid-life career retraining is really hard and scary to even contemplate.
