两极分化加剧的另一个原因是利益集团试图集中精力处理与物质和经济条件有关的各种问题。他解释说，这些利益集团是围绕包括人权和其他道德问题在内的社会和文化活动而构成自己的群体。早期的一些群体也属于这一群体，他们通过遵循愿意妥协的原则获得了很多优势(Layman et al .， 2006)。然而，这些利益集团在与社会、文化等相关的问题上存在分歧。威尔逊指出，在后现代时代，妥协是一种非常困难的倾向。
Wilson has tried to explain three different reasons for the increase of polarization in the present times. The first reason is the changes in the politics of the congress. In order to explain the same, he considers the division between republicans and democrats which was there during the times of impeachment of Clinton in the year 1998. The budget which was passed in the year 1993, did not have any single vote from the end of the republicans. He states that since 1950, it has been observed that there has been a slight increase in the overall percentage of votes which has lead to the majority of democrats against the majority of republicans (Wilson, 2005). Other than this, there has been the elimination of a large number of liberal conservatives and conservative liberals. In the present times only two opposite sides has been left out which are the democrats and the republicans.
He further adds that because of the split within the part there has been a lot of increase in the incivility of the congress. He tries to remind of the times when the congress made the worst kinds of remarks about one another and also beat their rivals by the use of canes and fists.
Another contention which has been provided by Wilson is related to mass media. He states that because of the competitiveness in mass media, they used to ignite the issue of polarization. He tries to explain that in those times when there were a very few television stations and news channels, the media tried to increase its gravity in the political center (Miller, 2013). But, in the present times the mass media has gone towards being adversary. He states that in the present world, media has a large number of lines of access which reflects the maximization of the controversies. This has also led to the cultivation and creation of niche markets.
Another reason for the increase in polarization is because of the interest groups which try to concentrate on the different kinds of issues related to material and economic conditions. He explains that these interest groups are the one who constitute themselves around the social and the cultural activities including the human rights and other moral questions. Some of the early groups who have been the part of the same has gathered a lot of advantage by being in the principle where they are open to compromise (Layman et al, 2006). Though, these interest groups has been divided on the number of issues related to society, culture etc. Wilson states that in the postmodern age, compromise is very difficult tendency.
In order to answer the question related to the spread of polarization beyond the political elites, he gives the argument that the polarization of elites is something that may go down to the people as per their levels of awareness about politics. He explains that whenever there is an increase in the education level in the country, more and more people will be politically aware of the situations in the country. He states that the people who are politically aware may be likely to be the ones who are well-educated and have gone to schools and colleges (Uslaner, 2015). Also, the educated people are interested in hearing about political information from the mass media. They are much more aware in the recent times and are more open to different kinds of political queues. This is another factor which has led to the disaggregation between different kinds of wealth and political interests.
Further, Wilson also cites a study which suggests that the people have different voting behaviors in the present times. The people in the past voted in the same manner like business managers but now they try to identify from their knowledge.
