In my opinion, there are few solutions.
Leaders should lean towards one or at least narrow down the languages for better communication which would lead to working together for a better cause. Like buying a machinery all together and using it all together.
Indian people are known as very hard working, so some percentage actually travels away from India for the search of better life and this is no secret that some of them end up very wealthy. They should help to make their home a better place.
I thought this might spark some discussion. Not responsible for content, but thought some of this guy's ideas interesting.
