What you fail to realise is that while yes, wizards are overpowered, monks are an incredible example of flawed design. Their class abilities have little to no interaction, they need all characteristics in the stratosphere except Charisma and nobody has any reason to be one beyond four levels!
What you're pointing here is that monks can beat wizards if they use tactics anybody else can use.
EDIT: I suggest you read Treantmonk's Guide to Wizards: Being a God. You'll notice how much God Wizards are team players instead of the idiots you put them to be.
