Microsoft is a prime example. I consulted at Microsoft about from 2005 to 2006 and in a meeting with upper management they were growing about how smart it was to use H-1B programmers. I told them that it hollowed out American workers in IT, and was now beginning to hollow out middle management, and that if it follows its natural progression the executive suite wasn't safe.
Let me introduce you to Satya Narayana Nadella. He is the foreign born Indian-American CEO of Microsoft who seems to be content in attacking and attempting to subjugate native born, cultural Americans. He became the CEO of Microsoft when he replaced the idiotic Steve Ballmer in 2014.
You can definitely give Satya props for not getting by on his looks. Some freaky women might fantasize about lubing up his smooth, shiny head but I do not think that got him where he is.
