Racism is more complex than an isolated act of violence, a single event. It is a historical and political process that creates a system in which some are benefited and others are socially disadvantaged.
There is no racism that is not structural. It is a very complex mechanism that creates vulnerability on the one hand and power on the other. There is no racism outside a power relationship. It depends on social structures so that discrimination remains systemic.
Prejudice of social class is related to purchasing power, access to income, social position, level of education, standard of living, among others.
Social class should be spoken in a broader sense, considering the various social groups in a socioeconomic classification, their position or status in the social structure, a fact that suggests the existence not only of two classes, but of so many others depending on aspects such as levels income, education, access to health care, among other factors.
In other words, we must think of the idea of social class prejudice beyond the bourgeois / proletarian key, considering the existence of more economically wealthy classes (millionaires, wealthy, upper middle class) and others with less resources (middle class, lower middle, poor, miserable), with income being the determining factor of their social position and, thus, of class prejudice.
