This is a very large topic idea, the difference in class between these two groups of peoples. For one thing, there is a religious gap, and their religions directly contribute to each group's socioeconomic status. Their housing reflects their economic and religious status; one group is "allowed" to live in an affluent section of town, the other is "forced" to live in an area that has become a ghetto. Questions to ask yourself when it comes to Marxist theory is, who is doing the "allowing," who is "forcing" these conditions on the people of the area? In other words, who is in power, how do they maintain that power (what coercive forces do they use to maintain their power? Violence is usually the first method, but where do they get their weapons from?). Once you establish who is in control, you start to see how the relationships between the two groups are intractable, and how difficult it would be to live there, and to cope with the social, religious, and economic restrictions they live with. So, class is a function of how the group has been defined; who they are to one another, determines how they are thought of, how they are classified, what segment of society they are "permitted" to live in. But class then becomes a very constrictive determination of "who" they are all allowed to be, and what they call themselves. By segmenting themselves, and staying within their group, they are safe from persecution, but rigid adherence to their group is ultimately stultifying, and contributes, I would argue, to the downfall of their society.
