I agree with this in general but it depends on the individual. If I were looking to hire someone who was extremely smart/an expert on X I'd be focused more on their value:cost than location. But for large tech companies that's not how you're hired - a body is needed to fill head count and the overlords determined that this particular position was better filled by a body in a cheaper country. Even if you do turn out to be very valuable to the company, the system is not set up to accomodate that scenario (and realistically, if you leave, the company can just hire another 5 people and hope to get another very valuable person among them).
