All increases in the number of people doing work and creating things can increase GDP per capita (especially if you count the increase in the income of the person who immigrated, as you should). Inexpensive Indian IT guy makes IT cheaper, which is good for everyone except those who directly compete (and even for them it's not really that bad). This makes it so more things that are complementary to IT can be done. Broad-based benefit that outweighs a narrowly-experienced cost.
