The lore might be unclear because I didn't write it from his point of view, we don't know why being called "the rich wizard" makes him angry. He actually thinks wizards are just good to make silly tricks and curses on people who were mean to them, so he wants to be called a mage as he defines them as powerful people who cast spells.
