That's one way to look at it, but another way is to ask the question - would you be happy to have your pay and entitlements made public to all of your neighbours? As well as to all of the scam artists and thieves out there? Complete with your address and the amount of hours you work (a good indication of when they can consider you might not be at home)?
Your neighbours might just complain about the poor state of your fence ("Considering how much money your making, you think could take a bit better care of it, no?") or try to hit you up for a loan.
But the Ne'er do wells out there will pay close attention, when it comes to knowing how much you earn, what you might have in your house, and when your likely to be working. That's ripe conditions for becoming a target.
So yes, knowing how much civil servants earn would be nice from a making sure we taxpayers are getting our money's worth (sorry, I mean how much we're getting shafted by), but for the individuals concerned it carries significant risks if not done carefully and properly.
