Caste is not a physical object like a wall of bricks or a line of barbed wire which prevents the Hindus from co-mingling and which has, therefore, to be pulled down. Caste is a notion; it is a state of the mind.
Caste may be bad. Caste may lead to conduct so gross as to be called man's inhumanity to man. All the same, it must be recognized that the Hindus observe Caste not because they are inhuman or wrong-headed. They observe Caste because they are deeply religious.
One thing that was very clear to me is that the young people in a place like Annawadi aren't tripping on caste the way their parents are. They know their parents have these old views.
I lived in a country where I couldn't live where I wanted to live. I lived in a country where I couldn't go where I wanted to eat. I lived in a country where I couldn't get a job, except for those put aside for people of my colour or caste.
