In The Canterbury Tales, how was Chaucer satirizing life in England in "The Prologue?"

It was in Chaucer the critical spirit of 14th century
became most clearly apparent. The men and women who make up Chaucer's pilgrimage
represent almost every class of society. Only the very highest and very lowest section
of the society is left out. But the important section of the 14th century England is
very much there in the Prologue. In other wards it can be considered as a veritable
picture gallery.

By representing the entire sections of the
society he tries to satirize the society. Firstly we see the knight who comes from the
holy war, he is described as fresh because it was a 'holy' war. Then comes a dashing
young man, son of the knight. He represents the youngsters of the 14th century England. 
The Church is represented by Madam Eglentine and her fellow nun. This indeed the real
picture of the church during that time. The worldly attraction overpowered spirituality.
We can also see an undisciplined monk and a jovial Friar. These people behave exactly
against the expected behavior of the religious people.

Then
we have the Doctor, the Man of Law, the clerk of Oxford and Chaucer himself.  All these
people represent the intellectual professions. At the end the Wife of Bath represents
the women of the 14th century England
