For strong, well-qualified employees, salary is fungible. Anyone can pay it. For employers, talent isn't quite so fungible. They can't get just anyone to fill those positions.
Intel pretty much stabbed many of their loyal employees.
Many of their best left for better treatment and pay.
Now the only employees they can find are those who are stuck or suck.
Some refuse to grasp that the market works both ways....that employees can choose too. I suspect jealousy.
