Is there any data about H1B for large workforce "suppliers" vs. for individuals? As far as I know, H1B doesn't allow you to be an Accenture in India, and ship people to the US (even if they'd be at Accenture in the US). That said, for companies like Best Buy, H1B is just a tool, and if they want to pay less, they will find a way to pay less. What they will not do is pay you more. Instead of moving people around, they might opt to move the office to a different country. Writing software isn't bound to any location, so maybe making moving people harder will just end up making moving offices more attractive, the net result being even less than what you have now. Maybe it's pure corporate greed, or short-term thinking or late-stage capitalism, but I doubt it can all be pinned on some sort of migration abuse.
