If you are just worried about keeping your salary up, that will go down no matter what, as the talent pool all over the world increases and companies will offshore more work, that not only means less salary but fewer jobs.
Most of those who argue against pg's argument here are concerned about lower salaries, no one is concerned about fewer jobs (because companies will move work offshore), less innovation (new product development moving away).
Creating boundaries and not letting talent in, is just a big downward spiral and if it accelerates to a certain speed it will be too difficult to turn it around. May be not in short term but in couple to few decades.
