A more thorough explanation:

Definition: The working class; those without capital who sell their labor to survive.

Examples:

• Factory workers
• Construction workers
• Service industry employees

The proletariat refers to the group of people who work for wages and do not own the means of production. They rely on selling their labor to earn a living. The examples listed illustrate this definition because they are all jobs that require physical labor and do not typically require a higher education or specialized skills. These workers are often paid hourly wages and may not have job security or benefits.
