One must keep it in mind that if you pursue in single direction and in one vertical, then if the market is not available, then one's livelihood will be in question. As a matter of fact, I was forced to join B.Com. by my parents. To satisfy them I completed that degree and further I did not turn towards any Accounting or Auditing line. Further I have done my PG in Economics. But there is no specific opening for my PG. Hence I joined LL.B and in addition to that I have done PGDPM&IR and at present I am working as a IR Manager in a private organization.
Basically the studies must be on free of cost and as per the will and wish of the students. The parents or the school authorities can guide them by what is the study meant for and what is the scope of the education for fetching their livelihood. Then the student must be permitted to select his own line of study. If he is best in academics then further he can be permitted to select his own way of life (whether to select for teaching as profession or self employed/business or service).
So in my opinion, sticking on the vertical articulation is not advisable and one will surely face difficulty if one select the wrong route.
