In the 1960s, many sociologists noticed that economic obstacles alone were insufficient in explaining disparities in the educational attainment of children from different social classes. which concept was introduced to explain these disparities?

Cultural capital was introduced to explain these disparities.

Explanation:

Cultural capital is described as the skills and attributes a human being possess that demonstrate cultural competence and social status. Some of these attributes include knowledge, behaviour education, and style of speech. Cultural capital creates social difference and inequalities. A typical example is the social status of someone who has accumulated knowledge.  

Another contributing factor to class difference is due to race, nationality, religion since they affect access to different knowledge. Furthermore, materials objects that one owns related to education like books and computer, clothing and accessories also describe the cultural difference.

panem is a communist totalitarian dictatorship where all the resources and how they are allocated belongs to the capitol. the districts exist only to provide goods and services for the capital and most of the citizens live in poverty. it is a police state where the "peacekeepers" use force and threats to keep the people under control. dissent is outlawed and those who disobey the law are executed, flogged, or turned into avoxes. the games are another means in which the ruling elite in the capitol exert their power over the districts. when reading the books i drew parallels between panem and the soviet union and north korea. in no way is panem capitalist. the people in the capitol are wealthy but the majority of them are involved in the government somehow. it was the same way in the former soviet union where bigwigs in the communist party and high ranking government officials were given access to goods, services, medical treatments not available to the general public. if you think panem has a capitalist economy you need to brush up on your economics.
