Nandan Nilekani made this point in an interview recently.
Vested interests by factions have divided the nation vertically examples that are prominent are language, caste, religion, IT-nonIT people, State etc. His point was to make significant integration at a horizontal level for example take healthcare, education, response to terrorism, transport, governance mechanisms, availability of credit among other developmental needs. If we as a country do this then we can possibly move ahead into a better future. Sounds possible.
Let us start small do you see vertical divides in your community stopping progress on the horizontal critical needs of the community. What are you going to do about it?
