That does not compute. The US is already the most expensive place to move employees even with H1B scams factored in, so if employers were price sensitive they would just hire those people in Bangalore, Dublin, and Vancouver right now. What motivates employers is the use of presence in the US as a perk as people badly want to get out of those other places. Individual managers also like H1B because it gives them a high level of power and control over those individuals.
