I believe young people should study the subject they are most passionate about. Sometimes that may be vocational, leading directly to a job- nursing, medicine to name but a couple- even then, the decision to study this subject at university does not mean that you have to be a doctor or nurse for the rest of your life- or at all. How many young people know at age 18 what they want to do for definite anyway? It's only now at the age of 52 that I really understand how young I was at 18! In any case, the majority of university degrees are non-vocational in that they are not related to one specific job. And that's wise- in today's world we need, more than ever, people who have learned to think critically about the world around them and to think for themselves -the very thing which Arts and Humanities subjects are all about. The notion anyway of a job for life is no longer a reality in any case.
Plus there's the notion of education. Education is for its own sake. It should help to make us human and enhance and enrich our lives. Life would be a miserable and utilitarian affair if everything was geared into making money and surviving-it's through educating children and young people in the arts that we create the audiences for the wonderful music, dance, drama and books that make the world a better place.
Coming back to the question of being top at a discipline- the top-flight heart surgeons would look pretty silly without the team of support staff, you cannot have a piano concerto without an orchestra and a ballet like Swan Lake wouldn't work with only the Swan Princess- you need a whole company of dancers who are never going to be international stars but provide an essential role together. Yes, there are orchestras and orchestras, some better than others, and the same goes with soloists, dancers and so forth. But if you only had people who are in the top rank, there wouldn't be the professional musicians, for example, who go round doing good quality but not necessarily international concert star level performances in my little local theatre- nor the touring dance companies (some excellent, some less so but all give enormous pleasure and a lovely evening out) who are prepared to go out to our local, smaller stages.
