The implications of outsourcing on the India's economy, could
outsourcing be a product of global marketing?

Personally, I got a decent paying job! :-D

I dont quite understand your usage of the term "global marketing"? 

umm, its like this, for every 10 outsourced jobs in india. at least 2
auxillary jobs are created, to support them. So it has been an
employment driver.
Then, in the absence of huge industrial growth, like China has seen,
this outsourcing has made everyone sit-up and look at the services
sector as a driver of growth.
