I'm sure the neocons would probably write this off as India being in the early stages of of Kuznets Curve (1), but it's probably a case of what Piketty found when writing 'Capital in the Twenty-First Century'. Ie, in developed nations, the rate of return on capital greater exceeds the rate of economic growth, which creates an increasing gap between rich and poor.
It's difficult to see how they will mobilise these people to become consumers, when nothing suggests a disruption of Indian wealth becoming increasingly concentrated.
