I would clarify this as saying in the retail world this is true - maybe it will change if enrollment drops, but likely not anytime soon. Hospital is different. It used to be you started much less (like $10 an hour) and could work your way up to match retail, now I think hospital starts out relatively equal and has a much higher ceiling.
lets just hope that continues - but who knows. I do think hospitals are much more picky about who they hire (just won't hire a anyone with a license) - at least I know at my hospital we will let positions go unfilled for months until we find a good candidate.
