Answer:
b) Labor unions were formed.
Step-by-step explanation:
Throughout history, industrialists and laborers have clashed over differing ideologies and values. To boost production and profits, the industrialists, the Robber Barons, believed in the freedom to operate their own firms. They felt that labor was a commodity, that salaries were determined by supply and demand, and that they had the right to define working hours and conditions. Workers, not commodities, needed a voice in their working conditions, health and safety, working hours, and wages. These conflicts of interest and values shaped US Labor Union History.
