When I was in education I noticed that there was a basic dichotomy between skills and intelligence. Those who were academically gifted went to university and other than those that did engineering and medicine pursued disciplines that gave them plenty of mental acuity but little practical skills. In contrast those who did less well in their school exams went on to technical colleges and apprenticeship schemes. These people learnt agricultural techniques, how to fix a car and to make carbon brushes and so forth.
This dichotomy is found less today I think. This is because of the way that business has started to take a keener interest in universities. Moreover, now that university tuition fees are no longer free in the UK young people are discouraged from studying ancient history, classics and other academic subjects that have very little relevance to the modern world or finding a job.
This attitude does change however depending on your country, there’s certainly a different attitude to non-academic subjects in some places. For example Australian students are often more drawn towards more practical subjects than in the UK. Why it’s not certain although many of them are focused more on travel and gaining employment in other countries. Many use apps like this one to access the BBC and job sites in Australia.
The case is that young people should decide early on what skills they have the most chance of refining, and their education while starting off broad in scope should finally focus on those skills. This is how to make the most of education from an economic point of view in the case of the majority. Of course, for people like Einstein the theoretical and the academic should be pursued because this is their true talent and in the long run humanity will benefit from any breakthrough in the field of human understanding.
