Broadly speaking, the United States aspires to be an egalitarian country with social mobility; the American Dream includes the idea from the Declaration of Independence that "all men are created equal" and have the "unalienable right" to "Life, Liberty and the pursuit of Happiness". The phrase "second-class citizen" has a strong negative connotation in national politics. In practice, socioeconomic mobility in the United States is relatively low compared to Nordic countries and Canada, and income inequality in the United States is relatively high. Educational attainment and income are strongly correlated, but relatively low funding for K-12 schools in poor neighborhoods raises concerns about a cycle of poverty. These apparent contradictions lead to divergent views on whether American society is divided into distinct classes or should be analyzed that way.
