What IS the Approach?

Though I read Benjamin’s article I am still slightly confused about the Marxism approach to literature. Is it like viewing a piece of work (literature or artwork) as a product of the period? Or, as a product of revolt against certain institutions or class differentials that the artist has experienced and created in response? Or is Marxist view a very rigid type of looking at literature through a view of pro-communist views? I fully understood the section about the cult surrounding an object and giving it a certain life, but is that also a product of the time of publishing or does this come after the works creation?

This is like when someone talks about "The Cloud"
