My whole job is screening and hiring, my employer often works with some of the best known blue chip tech companies in the world, and this totally jives with the patterns I've personally observed around working in and around the tech sector. As a whole, it's really hard for me to see what's happening right now as anything other than a protracted attempt to stop long-term wage growth and reduce salaries, primarily by opening certain fields to outsourcing and cheaper immigrant workers—i.e., H1B visa abuse, etc.
