Wouldn't this affect everybody across the board? I think the senior salary flat-lining and junior salary growing is pretty much the law of nature in any occupation - there's a salary band for a given skill, and those who start at the bottom and are any good progress fast, those who start at the bottom and are no good drop out of the race and go do something else, and senior people pretty much know they're at the top of salary range and need to move into management or open up their own consulting firm.
