Final answer:
The rise of the adolescent workplace in the United States was influenced by economic shifts, changes in child labor laws, and technological advancements, but not by a decreased demand for teenage labor.
Step-by-step explanation:
According to the textbook, factors that contributed to the rise of the adolescent workplace in the United States include economic shifts, changes in child labor laws, and technological advancements. These factors intersected with broader social trends to create new opportunities for teenage workers. However, the option that did not contribute was d) Decreased demand for teenage labor. Economic changes like the shift from manufacturing to service industries and increased competition due to globalization led to different demands in the labor market, but not a decreased demand for teenage labor. Moreover, progress in child labor regulation and mandatory schooling moved children from factories to classrooms, thus affecting the nature and availability of adolescent jobs.
The narrative surrounding the decline in child labor is also associated with a budding consumer culture and a general societal shift towards education and age-appropriate work roles. Throughout this period, while there were efforts to push back against child labor, the number of children in the workforce eventually declined substantially thanks to new laws, increased mechanization, and societal values promoting education over child labor in industrial settings.
