HR may be the only direct beneficiary, but if you don't receive something out of the deal, why would you do it? You, of course, wouldn't. The indirect benefits aren't always obvious, of course. Perhaps someone in HR is your friend and they being happy from having a less complicated job allows for you to gain a stronger friendship, and so you don't mind helping them out to your ultimate benefit. Who knows what is specifically motiving people, but we do know that not even the greatest saint can successfully push himself to do something that is completely free of benefit.
