He's expecting that they will one day come home and build India rocketships and factories and all sorts of things that'll make India rich and powerful, but all they are doing is stealing half understood things.
This is only partially true; Modi doesn't expect it, but he does wish for it.
Something I learned fairly recently is why jeets are prone to narcissism; it's because nearly every single one of them suffers some form of cognitive dissonance as a result of claiming a rich, intelligent and ANCIENT cultural heritage while having been conquered by outsiders, including Muzzies and the Bri'ish, etc. This is why they always overcompensate and LARP as doctors, engineers, etc. when the truth is they're dumb as shit and their "culture" revolves around piss, shit, and filth. But they have to protect their delicate, extremely fragile egos so they project their ideal of power and intelligence, which is the basis of narcissism.
They want to find a way to elevate themselves out of the abyss of their own existence, but are incapable of doing that without ruining the world around them as a result. This is why they destroy nations and hate all other people, because they see the success of others and know that the sun has set on their retarded fake and gay "empire."
This is why they're so desperate, because they project their faiulres onto others while trying to portray themselves as having achieved success by some retarded garbage standard they believe to be ideal.
Westerners don't understand this because the west has been the lighthouse of civilization to begin with. We can't comprehend this level of failure because it has eluded us for so long. Intelligence cannot beget stupidity. This is why our leaders fall for the schtick
