How do the 'dramatic effects' of the dealer and Kino differ?

The pearl dealer, who symbolizes the ruling elite classes, proves to be another example of a manipulative professional man akin to the priest and the doctor. He shamelessly attempts to cheat Kino out of his money, offering a price that seems far too low for such a pearl; although there remains the possibility that the pearl may be an oddity with little practical value, the numerous attempts to steal the pearl, perhaps instigated by the pearl dealers, suggest otherwise. Kino's refusal is no small feat; as Juan Tomas declares, he has defied the structure of life around him. This places the parable in a larger political context, suggesting that a hierarchy around Kino works to exploit him and others of his station and resists any attempts to shift this social order. This idea is bolstered by the story concerning the pearl agent in which punishment is inflicted upon those who attempt to secure a better station for themselves.
