The city of Nagpur is one among various being groomed as the next wave of future metropolises of India. Hopefully, some meticulous planning and design will create a new generation of melting-pot cities that are more livable and capable of sucking in the tens of millions who will migrate there to work and live. I'm strongly in favour of a melting-pot society, as opposed to our current ever-fractious, tribalized model, and big cities are the way to go for that. More people will work and live together in close contact, and will absorb culture from each other, fusing into a common Indian identity. The forging of a strong and unbreakable alloy, as Jagmohan said.
With strong urban planning, the next generation of cities will rise like new Benares, organizing the population into streamlined productive existence coupled with convenience of amenities. These engines of assimilation and advancement will convert India's vast human potential into a successful reality. There will be no possibility of wheel-jam strikes, or ethnic ghettos as no-go areas for police.
When you think about it, the teeming hyper-congestion of India's current few metropolises is due to the lack of alternatives. Rather than exclusively trying to reform these ailing giants and taking on their numerous entrenched interest lobbies, instead a second wave of cities can be prepared in order to promote better lifestyle and a promising vision of the future.
Not so coincidentally, Nagpur is the birthplace of RSS as well.
