There's no reason why it shouldn't, but why should American corporations subsidize it?

Because they can hire 5 programmers in India for the cost of 1 in America, and American programmers aren't 5x better than Indian ones ? Amazon is an online shop, not a jobs program. I'm sure they would rather eliminate a position altogether even more than sending it to India.

Let me rephrase that. Why should American citizens allow American corporations to do that?

Seems just to me, honestly.
