It's actually the education system that is largely responsible for the "extremely corrupted political system", among other issues.
Does the schooling method promote corrupt behavior?
Most universities do not go after high performing engineers to join the faculty , but just mass recruit new college passouts who later climb the job ladder to reach senior positions.Add to this all the reservations based on caste and religion. Except for IITs and some government run engineering colleges, its a very weak educational system in place.
The situation in government departments is not different. New college passouts prefer well paid private jobs than the ones in public sector.
Bad teachers and less talented engineers in public sector: A recipe for corruption.
Our country does not need any more corporate drones, we need better politicians.
