This is not true for the industry we're talking about (or at least not as true as you seem to think). It really is in companies' best interest to be attractive to skilled workers in this industry and there really is a chance they will find themselves struggling if they get the wrong reputation. It seems (to me) like this is a major undercurrent in IBM's struggles, for instance (and outsourcing has not been a silver bullet). Thinking the balance is more skewed than it actually is is one of the things that skews the balance.
