How did the social and economic ranks of these groups shape their lives?

 Okay since I don't know what the full question is, I can tell you this about social stratification and economic ranks: 
 
 Social stratification, in its most general sense, is a sociological concept that refers to the fact that both individuals and groups of individuals are conceived of as constituting higher and lower differentiated strata, or classes, in terms of some specific or generalized characteristic or set of characteristics. Borrowed by analogy from the earth sciences, the term “social stratification” has come into general sociological use only since about 1940, although the matters to which it refers have been discussed under the heading “social class” for a very long time. However, in contrast to its earth-science usage the sociological usage of the concept of stratification often includes, implicitly or explicitly, some evaluation of the higher and lower layers, which are judged to be better or worse according to a scale of values. Such matters as relative moral worth, relative equality and inequality, and degrees of justice and injustice are often involved in the concept of social stratification. The concept is therefore widely used in political, ideological, and moral debate and controversy, as well as in social science analysis. But despite the difficulty of separating the context of moral and ideological controversy, on the one hand, from that of social science analysis, on the other, considerable progress, both theoretical and empirical, has been made in the study of social stratification during the last one hundred years. A brief history of this progress provides some necessary background for assessing where social stratification theory stands today and for laying out a conceptual model of what that theory might be in the future.
