Engineering a nightmare

These engineering especially software engineering has become a trend. 7 out of 10 parents want their son/daughters to study engineering. But how difficult/easy it is to become a  engineer when your own dreams and  interests are different. It is very very difficult. Engineering is not a joke it is very hard, to become a great software engineer as you expect your children to be recruited for one of the major software gaints and go to foreign countries. You have to study hard, pass the examinations with the university you are enrolled to. Now-a-days many of the colleges are becoming autonomous this gives more right to the internal teachers, who hardly know lecturing the capacity to pass or fail, a student. Good engineers will become bad if the lecturers have a grudge on them. Is the system changing to become bad or good.
