The term "middle class" refers to a socio-economic group that falls between the upper and lower classes. It typically includes individuals who have stable jobs, earn a decent income, and possess some level of financial security. The middle class is often characterized by its ability to save money, invest in education, and participate in consumer culture through discretionary spending on items such as vacations or new cars. In many societies, membership in the middle class is highly valued because it provides a sense of economic stability and social status. However, the definition of what constitutes the middle class can vary greatly depending on factors such as income thresholds, lifestyle indicators, and cultural norms.
