Membership in the underclass can be long-lasting or even permanent for some individuals. The underclass is a term used to describe a group of people who are typically unemployed or underemployed, live in poverty, and have limited access to education and social services. Many individuals in the underclass face systemic barriers that prevent them from achieving upward mobility, such as discrimination, lack of access to quality education, and limited job opportunities. For some, membership in the underclass may be temporary, but for others, it can be a long-term or even a permanent condition.
