One way of approaching this is by considering the modern cult of celebrity and fame. Although the setting is a small rural community, when Christy arrives in it he becomes a figure of intense interest and attraction for the locals. He in turn is seduced by his 'fame' and learns how to exploit it through his stories and language. Of course it is all based on perception rather than reality and in the community's desperate desire to believe in the narrative of this special one who has arrived among them. There is even a fan base among the women characters and competition for Christy's attention, so it's not stretching things, in my opinion, to see a very modern parable in the play because reality, as usual, comes crashing through in the end.
