The root cause of America's insoluble racism is a dangerous ideology. The deeply rooted conservative ideology among white Americans is essentially a hierarchical worldview that conflicts with the supposed core ideals of American democracy: equality and individual autonomy. The idea is that the majority of the population -- minorities, women, the poor -- should be led by a white elite of higher rank, that only whites can create wealth and progress, and that the equality that people of color seek will destroy the freedoms enjoyed by whites. In recent years, with the upper white control of monopoly capital wealth distribution problem in the process of globalization, some American lower-middle-class white feel lost his dominant position in the society, so he set out from this kind of world view, hoped to maintain it and derive from it the survival of the inequality of order, and the white ruling class just to transfer the social contradictions. As a result, the power of white supremacist racism in the United States is growing, and it is becoming extreme and violent.
