Another phrase for "the texts are a microcosm for marxism"

I hope everyone is doing well. I’m currently trying to write something but I’ve got a bit of a writer’s block lol. Could someone help me rephrase this into a more concise and smoother sentence:

"The texts are a microcosm for marxism"

The idea that I am trying to convey is that the texts are a metaphor for marxism. I would like to sound concise but also sophisticated but not too sure what to say 🙁
