When you look at this country you will realize that many sectors are dead or not functioning hence this has a way of destroying job opportunities such sectors create or lets say limit the job opportunities. When you look at the odds of getting a job after studying such course relating to that sector you find out that you end up with nothing unlike in the Western world. For example someone studying sociology in Nigeria, nothing for you or history which can be someone's passion. That's why most parents push their kids to what we tag major courses because of the job opportunities available.
