Another editor. That thing behind his ear is his pencil. Whenever he finds a bright thing in your manuscript he strikes it out with that. That does him good, and makes him smile and show his teeth, the way he is doing in the picture. This one has just been striking out a smart thing, and now he is sitting there with his thumbs in his vest-holes, gloating. They are full of envy and malice, editors are.
The law of work does seem utterly unfair-but there it is, and nothing can change it: the higher the pay in enjoyment the worker gets out of it, the higher shall be his pay in cash, too.
