Explain how one of the pilgrims from the prologue represents an issue of medieval society

The narrator opens the General Prologue with a description of the return of spring. He describes the April rains, the burgeoning flowers and leaves, and the chirping birds. Around this time of year, the narrator says, people begin to feel the desire to go on a pilgrimage. Many devout English pilgrims set off to visit shrines in distant holy lands, but even more choose to travel to Canterbury to visit the relics of Saint Thomas Becket in Canterbury Cathedral, where they thank the martyr for having helped them when they were in need. The narrator tells us that as he prepared to go on such a pilgrimage, staying at a tavern in Southwark called the Tabard Inn, a great company of twenty-nine travelers entered. The travelers were a diverse group who, like the narrator, were on their way to Canterbury. They happily agreed to let him join them. That night, the group slept at the Tabard, and woke up early the next morning to set off on their journey. Before continuing the tale, the narrator declares his intent to list and describe each of the members of the group.
