People's income affects many aspects of their identity, especially in countries such as the United States where inequality is rapidly increasing. Much of Western society is de facto segregated by income. Where you go to school, whether you continue on to university, what clothes you wear, what type of house you live in, with whom you associate, and your leisure activities are often determined by income. Thus much of your sense of social self is affected by how much money you have available. In high schools, for example, much of the structure of voluntary affiliations (cliques) involves the banding together of students whose parents are from the same socio-economic class.
