I regularly use the postal service to mail letters. I doubt that couriers deliver letters outside the urban centers in the rural heartlands where most people live. To even imagine labourers using courier service takes considerable effort on my part. I think that urban India is getting completely disconnected from the "real India". Its reflected in the growth of the "walled communities" growing in places like Noida, that a foreign newspaper (The Washington Post) commented on recently. The truth will hit hard in the next elections.
