I disagree to your disagreement :p

The talent war is continental rather than global. There are plenty of VISA issues and legal troubles that make it impossible for a lot of people to work in a lot of countries [and for those who do, it's preventing them to get the top end of local salaries].

Thus there is no global salary.

there is no global salary. But if a company in say, New York City, needed a special skill, you can bet they would pay NYC prices to get it regardless of location. For the rest of us saps, your comment rings true (this coming from a guy who makes less due to his location)
