They’re not getting anything from it either. The only people benefiting are the Indians. Corporate loses money because H-1Bs have negative productivity and piss off customers.
The real trick is once the Indians get in, like all good parasites they hijack the host in order to reproduce. Jeets get in, get a Jeet handler (another Jeet, usually a Brahmin, the Jeet Jew/Priest caste) to "deal with the communications issues" -- i.e., handle the Jeets cause no one wants to and they ignore American managers, then the Jeet handler will arrange shit so Jeets get credit for anything that gets fixed, non-Jeets get fired or laid off, and eventually they get a Jeet in HR and it's over.
But on paper this all probably looks fucking amazing finance wise. "We can pay them 1/10th what we pay an American!" Good luck with that, as you mentioned. All you get is the ever decreasing number of Americans playing catch up to try and make Jeet work, er, work. Eventually this reaches a boiling point and everything collapses and the company dies, but the Jeets don't care, there's always another H-1B scam they can join in on.
There are three company types in the world today:
1. Those that have not yet hired Jeets
2. Those that have hired Jeets and are being hollowed out and gutted so Jeets can consume the host whole
3. Those that survived the second stage and swore never again to hire a fucking Jeet
