There is a big difference between foreign workers who are great and add value, and foreign workers who are brought over, are subsequently exploited, and who are also used to depress the income of the local workforce. Seen it happen. Then there are the "Indian Mafias" in places like Microsoft, where over 50% of an organization is Indian because they got into a cultural hiring spiral. And the products from those groups are generally pretty awful, because everyone seems to want to be a manager or see how high the next re-org will take them, and not do good designs or write good code. H1Bs shouldn't be used for job shops, and they shouldn't be used to bring in cheap labor, but that's largely what they're used for now. A lot of really good Indian engineers are going to get hurt, and that will suck.
