Stratification refers to systematic inequalities between groups that arise from social processes and relationships. Social stratification creates a hierarchy in society where groups have unequal access to resources, power, and social worth. It can take many forms like class, race, and gender, which overlap and influence life chances. There are functional and conflict theories for stratification - functionalism sees it as motivating productivity while conflict theory sees it as exploitation. Inequality in the U.S. is growing, with the wealthiest 1% controlling most wealth and CEO salaries far exceeding average incomes. Poverty disproportionately affects minorities and reasons for homelessness include unemployment, lack of affordable housing and support.
