On a related note, we often hear about folks losing their jobs and having a hard time retraining. A college degree is theoretically supposed to teach one critical thinking and self-didactic skills. I wonder if vocational education is less robust to economic shifts than a college degree? Certain trades like cooking, plumbing and electrical work are always going to be in demand, but suppose one trained as a machinist and finds oneself unemployed as society deindustrializes. Is it harder for a machinist to retrain than for an English major to pick up basic clerical skills?
