Bro i don't agree with you when you say "most of the sectors don't need engineers." In stock trading machine learning is used to predict stock prizes and also in health sector it is used to to predicts symptoms to cancer early so that it can be treated easily. Restaurants and hotels use web developers to go online.

I would say if anyone has interest in any field of engineering the you definitely must pursue it, even if you are from a Tire 3 college sooner or later you will get successful in your field.

Thats what i think @techytushar
