Everyone seems to be making the assumption that all the work IBM India does is outsourced from US. IBM India is the biggest domestic IT player in India with clients like Airtel, Indian Railways, HDFC etc.; IBM India also services clients from other countries in the world (which wouldn't have happened otherwise because its too expensive in the US). And, IBM India, has a few research labs setup that do independent research.
Considering this, how is the number of employees in India and US even a relevant question. Isn't it similar to say why is there more manufacturing workforce in China when compared to US for company X? We know why, it costs less for the company and the client, and taking advantage of it opened up new markets/demand.
