In The White Tiger the narrator differentiates between a Dark India and a Light India.
“Please understand, Your Excellency, that India is two countries in one: an India of Light, and an India of Darkness. The ocean brings light to my country. Every place on the map of India near the ocean is well off. But the river brings darkness to India—the black river (12)”.
I’ve found that recently this theme has been pursued on multiple levels. For example, in this campaign, the famous Bollywood actor, Amitabh Bachchan takes measures to make a distinction between the two. http://www.youtube.com/watch?v=wP-TwHwLc98
Additionally, it seems like there is truly a diversity of income level and life style choices in India. I came to know of the Maharaja Express, which is a luxury train trip that takes travelers across prominent cities in India. The stark contrast between this luxurious vacation package and the poverty of so many in India is just one example of the gap between the rich and the poor.
