第二次世界大战后，中产阶级的崛起改变了西方社会中富人和穷人的两极社会结构，一直被视为维护西方社会稳定秩序的主要社会因素。近年来，随着经济全球化的发展，全球经济因素的流动，西方中产阶级就业机会的丧失以及社会地位的危机，都激起了他们的愤怒。 2019年6月12日，斯坦福大学胡佛研究所历史学家Victor Davis Hanson发表了一篇论文《华盛顿时报》，分析其原因和后果。
All these complaints reflect the reality facing the middle class in Western society. In social policy, that is, the rich have the ability and social influence to be plagued by higher taxes and fees, or can avoid them altogether, and the middle class is always at a disadvantage. For example, the green development policy proposed that the people should tighten their belts, but did not ask the elite to cut the second and third houses and the use of overseas vacations, luxury cars, private jets and high-tech equipment.
In the field of education, managers of Western public primary and secondary schools and universities tend to prefer private schools to conduct strict traditional training for their children. Elites send their children to the university by their connections. The university has catered to their needs and increased the diversity of managers, which has led to a multiplication of the university's various expenses. Students in middle-class families who are in debt can only borrow money to pay various fees.
On the issue of immigration, the elites who support the open borders are convinced that these immigrants will not have a substantial impact on their own communities, schools and privileged lifestyles, and cannot understand the mental state of so-called xenophobic, racist or nativist . However, only non-elite groups have directly experienced the sudden influx of illegal immigrants into their communities, directly affecting social resources, schools and security.
