Canterbury Tales

So I am not trying to change the subject, I feel that we have had some really great discussion about SSGK, but I feel that it is time to switch to a new piece of literature.
From the background information, we can see that Chaucer was not born into the aristocratic society, rather he worked his way into that society. In class the past two days we have been reading the Prologue to the Canterbury Tales and talking about the ostensible sins/real reason for being on the pilgrimage. In this prologue Chaucer describes all different people from the three classes. For example he first describes the knight was from the aristocracy. It seems interesting though that Chaucer would use the naive "pilgrim voice" to describe the ostensible sins as the reason for the people to take the pilgrimage; and then use the "poet voice" to hint at the real reason for going. Wouldn't Chaucer be taking a huge risk by exposing the higher classes "skeletons"? I could see if he exposed the real reasons for the lower classes because he was in a higher class; but for the aristocratic class? In a sense it is like the poet voice is the paparazzi in a sense, always trying to expose the dirty, real reasons why a person does something.
