The economics term for this is "labor arbitrage" and it has gutted many high-tech companies with rich-kid executives treating workers as fungible resource pools of interchangeable servants. US hardware engineers and US software developers are replaced by hordes of low-paid overseas technicians, especially in what are perceived as support roles such as data management, specs documentation, and quality assurance testing. I can corroborate the truth of this from personal experience, from my time at both Hewlett-Packard and Qualcomm. Entire US departments disappeared in just a few days. Fortunately I continue to self-train in new technologies as a lifetime hobby, and so have managed to stay just ahead of the worst of it, for now.
