OK, but then what is the long-term business justification for paying more-experienced staff less than less-experienced staff? I get that the short-term justification is "we can get away with paying the former less because enough of them will be afraid to leave." But is there another justification? In my experience, at large companies "cash flow" would not even vaguely register the difference of increasing salaries for experienced people you want to keep, and it would be a marvelous signal to the rest.
