How are Hazaras treated in Kabul in Khaled Hosseini's The Kite Runner?

Khaled Hosseini's The Kite
Runner attempts to paint a true picture of life in Afghanistan during the
final decades of the 20th century, and his descriptions of Hazara life and the
discrimination against them appear to be accurate. In the novel, Ali and Hassan are both
considered inferior by many of the people they encounter; Baba, of course, loves them
both and considers them part of his family. The Hazaras became a particular target of
the Taliban, and both Hassan and his wife are later executed by
them.

The Hazaras, primarily Shia Muslims, make up less
than 10% of the population of Afghanistan--far less than the ruling Pashtun and Tajik
tribes. The Hazaras are believed to have Mongol roots, and an ethnic cleansing of the
group was undertaken in the 19th century by Emir Abdur Rahman. Today, the Hazaras still
mistrust Afghan rule, and they faced social, economic and political restraints
throughout most of the 20th century. In the 1990s, the Taliban publicly targeted the
Hazaras for ethnic cleansing, and Hassan was just one of the examples of this
action.

Today, with the new American-backed Kabul
government, Hazaras enjoy a better life, with increased educational and socioeconomic
opportunities. Their original homeland, Hazarajat, however, is still woefully
underfunded by the government, and the Hazara there  primarily raise
livestock.
