Final answer:
Minors under age fourteen can only be employed in agriculture, subject to specific limitations and with parental consent, due to federal laws aiming to protect child workers and promote education.
Step-by-step explanation:
Minors under age fourteen can only be employed in certain specific situations due to historical efforts to protect children from labor exploitation and promote education. With historical precedents such as Prussia's Child Labor Act of 1839 and various laws passed in the United States by the early 1900s, the focus has increasingly shifted towards keeping children in school rather than in the workforce. In the United States, after many failed attempts and amidst concerns such as those raised by the case of Ahmed Zia, a federal law was passed in 1938 to restrict the employment and abuse of child workers. This law sets age limits to encourage schooling and places specific limitations on the types of jobs that younger children can do. Under this law, minors under age fourteen can be employed in agriculture, but there are strict conditions that must be met, including limited hours and the requirement of parental consent.
