Final answer:
Individuals who sell real estate for others are required to hold a license to legally collect compensation, as occupational licenses ensure quality standards within the labor market.
Step-by-step explanation:
People who sell real estate for others must be licensed in order to collect compensation. Occupational licenses are a critical aspect of the labor market because they establish a standard of quality. These licenses are often required by government agencies and are proof that an individual has completed the needed education or passed certain tests. This includes licenses for various professions such as doctors, teachers, nurses, engineers, accountants, lawyers, and real estate brokers. Therefore, to engage in the selling of real estate on behalf of others for compensation, a person must be properly licensed, regardless of the amount of compensation or the number of transactions.
