Sinclair's Ability to Bring About Change

I agree with Sinclair in that if outsiders don't empathize and feel bad for the people crushed by the system then we as a society will be less inclined to change that system. To unpack this statement, Sinclair is calling on society to acknowledge that the system is broken and that it is "crushing" people as a result. The system he is referring to is the class and employment structure in American industry. If outsiders fail to recognize this broken system and choose to ignore that the system needs fixing then as a result of this failure we will be less inclined to change the system.
Sinclair takes his statement and takes action upon it. He works throughout his novel to provide data and information to the uninformed, helping to educate them about the "system" and the factory workers that are being "crushed" as a result. Through Sinclair describing scenes where workers work as fast as possible for poor wages in dangerous conditions the reader can begin to see the flaws to the system and its unbalance. As the reader begins to be able to see this they can start emphasizing and taking action towards wanting to see change.
Through Sinclair's ability to get the reader to empathize as a result of seeing the hardships and unfairness faced by the people being "crushed by the system", they can be more likely and inclined to want to change the system so that it can be more balanced.
