"...the monster that sent the tractor out, had somehow got into the driver's hands, into his brain and muscle, had goggled him and muzzled him, goggled his mind, muzzled his speech, goggled his perception, muzzled his protest." pg35

The repetition of the words "goggled" and "muzzled" help highlight what they feel towards the banks. These words are described as actions done the bank to make their lives worse. This makes them seem evil as if they are playing with there minds like they are toys or something. The use the words repetitively as if they were punches. Each punch making them more and more confused. The repetition help shows how the banks are metaphorically beating them up.
