Final answer:
The protesters are promoting a laissez-faire/free market philosophy, which opposes government regulation of business practices, including labor laws limiting working hours.
Step-by-step explanation:
The protesters demanding that the government end a policy setting a limit on the number of hours per week employees can work are promoting a laissez-faire or free market philosophy. This perspective argues against government regulation in the belief that individuals should have the freedom to work as much as they want and businesses should have the flexibility to operate according to market demands without restrictive labor laws. Such a philosophy is characterized by the idea that less government interference will lead to greater economic efficiency, higher profits for companies, and more opportunities for workers to earn income.
