The Black Queen and textbooks

From the Duchy Crier:
Textbook inventory management is site-based in the Duchy, as it is in many other duchies and central support for these local processes in the Duchy has been provided by the Black Queen.

Oh, really? The Black Queen?!! My dear, it is to laugh! I wonder if Sage knows this? Since the new part time Keeper of Textbook Inventory will be making $45,000 that must mean Sage is making $90,000, since she's a full time Keeper of Library Management. I had no idea Sage was so well paid! Not that she isn't worth it, of course. In fact, since Sage is already handling central Library Management and, in addition, Textbook Management, the job supposedly being done by the Black Queen, that should mean that Sage actually should be making $135,000 a year. She should demand a raise immediately!
