What exactly does The Kite Runner say about issues of social class, and how does this relate to us in society today?

The
issues of social class are central to , especially concerning Amir and
Hassan, and to a lesser extent Baba and Ali as well. It is the core of all problems and
suffering in the novel, with the exception of simple human cruelty, which transcends all social
class. It is worth noting, however, that other things transcend those lines as well but are less
obvious, at least to societies in large. For example, the reader notices quite early on that Ali
and his son Hassan are portrayed in a more positive light than Baba and Amir. This contrast only
gets sharper as the action progresses, especially concerning Amir, who has to spend the second
half of the book making up for mistakes he made in the first.

This isn't to
say that people in power are always worse than those who are oppressed, but it shows that the
lines social class draws are completely fictional and arbitrary. History has shown us time and
time again that every class from kings to slaves births heroes and villains...
