Frankly your vision is limited to the outsourcing industry. Would it surprise you to learn that many many big companies (GE, Msft, GOOG, FB, pharmas, etc.) that form a large percentage of the US economy also hire people with specific skills (say, 3D computer vision or expertise in pharma processes) who by being educated in the US universities are some of the best in the world? No manager in these companies is thinking about the leverage you&#x27;re talking about when the person&#x27;s skill can be a do or die for entire product lines.
