Here's a breakdown:
* Manual Labor: This includes jobs like factory workers, construction workers, cleaners, and agricultural workers. They often rely on physical strength and skill to perform their duties.
* Industrial Sector: This refers to jobs in factories, manufacturing plants, mines, and other industries that produce goods.
* Service Sector: This includes jobs in retail, hospitality, transportation, and other industries that provide services to consumers.
The "working class" is distinct from other socioeconomic classes, like the upper class (wealthy individuals) and the middle class (those with moderate income and professional jobs).
It's important to note that the definition of "working class" can vary depending on the context and time period.
