India is the largest producer of engineering graduates in the world. Over eight lakh adults graduate as engineers in India, which, believe it or not, is more than the population of over 70 countries of the world! But if different studies are to be believed, and honestly, we have no reasons not to believe them; over 60 to 80 percent of those graduates are unfit for employment! So the burning question of the hour is who is responsible for such a catastrophe? As you dig deep to find the answer, you will end up blaming each and every stake holder of this ‘business’. Parents, students, education system, government, corporate world; all of them share the responsibility of this simple, yet devastating misfortune of the aspiring individuals of this generation. Most of the parents in India still believe in already tested career paths and for them engineering is the safe haven. If we think about it we can adopt the metaphor of the sheep following the herd. Accordingly we can say that our parents are the shepherds and thus, students, the sheep, follow the herd. Students, around whom the whole story is revolving, needs to understand one thing very clearly that the education system is responsible for giving them degree, getting education is completely their own responsibility because at the end, it is students who have to suffer. So getting updated with the current corporate scenario is the need of the hour. The teachers are the catalyst of any change. They have the ability to mould the future of their students. And as quoted by Kalam Sir, ‘A teacher has to create a lifelong autonomous learner.’ They need to stop creating type writers. They need to motivate, carve the way to include recent technologies in their teaching rather than sticking to decade’s old syllabus. Education system needs few drastic changes. They need to focus more on practical education rather than adhering to century old teaching system. They just cannot get rid of their responsibilities by conducting examination and providing degree. And at last our government, being the safeguard of the society; they must put a check on this in order to save the future of the country; because if the same trends continue, India might become the largest producer of jobless graduates. The colleges lacking basic infrastructure for technical education must be closed.
