Discuss the issue of freedom for lower-caste people versus the upper-caste people of Nepal. You must have a clearly stated, one-sentence, argumentative thesis statement.

The Nepalese caste system creates a society in which the upper-caste people have a vastly greater amount of freedom than the lower-caste people, which limits opportunity and prevents improvement for those in lower castes, showing a fundamental flaw in their system.
The caste system in general has a variety of flaws, including enforcing segregation and discrimination. However, in regards to freedom, the upper castes clearly have a much higher level of freedom than the lower castes, and this creates inequality and an inability to improve. Without the freedom to marry outside your caste or find employ that is more beneficial than your caste typically is involved in, you have no opportunity to move outside of that caste. Essentially, lower-castes are forced into a form of "ethical slavery" wherein their lower-rank and supposed previous bad morality (in a former life) force you to engage in servitude and become a low-class citizen with no chance of rising from that position.

While a caste system continues to exist in Nepal, since the 1960s, discrimination based on caste has been illegal. In practice, however, caste remains a very good indicator of economic success and status, and in many respects, caste is the basis for obtaining well-paid employment and for upward mobility. People from the lowest caste, Dalit, are generally the poorest and are very underrepresented in middle- and upper-class occupations, as well as in Nepal’s government. Many commentators expected the situation to improve after 2008, when the monarchy was abolished in favor of a republic, but widespread conflict has inhibited effective change.
The issue of "freedom" mentioned in the post seems to apply to the question of sustained, caste-based discrimination. There are several ways to approach an essay about this topic. One type of thesis would simply state that caste-based discrimination continues to be a major social problem. Another type of thesis could begin with a similar assertion and then argue that the system is harmful to Nepalese society overall, not merely to lower-caste people. A third type of thesis would focus on the position of the lowest castes and suggest concrete recommendations to improve their position.
