What was the main benefit of the factory system? It cut costs and made workers more efficient. It gave people their first chance to support themselves. It reduced pollution caused by family-based power sources. It increased the value of the workers and as a result, salaries rose.

The correct answer is It cut costs and made workers more efficient. People could support themselves even before and it increased pollution to unprecedented levels. It actually decreased the value of the worker since the work became simpler and workers worked for less money since they were easily replaceable. Factories brought great profit to the economy and the factory owner, but not much for the workers.
