A wizard is not very good at passively having his damage spells deal 60%+ more damage per CL. It's easy to build a sorcerer that deals Burning Hands of average 18 fire damage level 1, which, at level one equates to "Save, and still die."

As for Monk's power, I don't really care. If we've got a primary spellcaster and a two handed weapon barbarian, all the party's combat needs are accounted for and everyone else is there for flavor and utility.
