The situation is really bad for the Indians if you think about it.
West is going to get absolutely fucked by the economic collapse to a point of civil wars, which will end up eradicating all non white groups, by either kicking them out or even killing them.
India itself is on the edge of a gigantic civil war, due to mass unemployment and hundreds of millions of really angry young men and this scuffle will lead to a war with Pakistan due to the proximity and religion alone.
China on the other hand is growing like crazy and will be the next major world power for decades.
It's an entirely realistic situation that India loses hundreds of millions of people in the upcoming conflicts and basically reverts back to the early 1900's, with no ability to export population.
I think they'll simply become a manufacturing hub for the Chinks, the way China is now for the West.
