It is absurd to argue that the “evaluation of teachers can wait”. Of course “there’s a lot that is wrong in the education sector in India, be it at the primary or higher education level”. In General the Indian education system has been sucked out of good quality education. The unionized teacher group is major part of the damages.
In fact it is not true that “there is every chance that they could be victimised” supposes if that is the case is not that the children are now victimized in schools, colleges and the universities? They are.
What importantly Adam Smith said was that “the teachers had no jurisdiction over their pupils, nor any other authority besides that natural authority, which superior virtue and abilities never fail to procure from young people towards those who are entrusted with any part of their education.”
