One theme that is shared between Marti's writing and Sinclair's work is the undeniable call to action. Sinclair does not accept that capitalism as a socio- economic structure will automatically prevail. He believes that if the working class can follow Jurgis' example, there will be change. This is evident in the characterization of Jurgis that shows him no longer as a victim, but rather an active agent of Socialism. In much the same way, Marti is advocating a collective form of change through solidarity:
It was imperative to make common cause with the oppressed , in order to secure a new system opposed to the ambitions and governing habits of the oppressors.
In both works, there is a clear theme that individuals cannot capitulate and accept things as they are. Rather, there has to be certain imagination that both writers are demanding their respective audiences to have in embracing what can be as opposed to what is. In this, there is a shared theme of transformation in both writers' works.
