The working class refers to a group of people who are employed in jobs that typically require manual labor or lower levels of education. This class often includes workers in industries such as manufacturing, construction, and service sectors. They usually earn hourly wages rather than salaries and may have less job security and fewer benefits compared to higher-income groups. Historically, the working class has played a crucial role in the economy, contributing to the production of goods and services. Their labor is essential for the functioning of society, and they often advocate for better working conditions, fair wages, and labor rights through unions and other organizations like the AFL-CIO.
