Well, I do work in a field that competes with foreign labor. I'm a computer programmer. I compete against thousands of people willing to make half my salary. I beat them by being a better employee who does demonstrably better work, and charge a premium for my services because of it. All competition has done is force me to be better at my job, so I don't really see the problem.
But your being good does not save the bottom line and you could still lose your job because some jackass wants the cheap labor.
