The map shows Karl Marx's evaluation of the process of historical development of the society into two classes, mainly, haves and have nots. 

Here, Marx states that base i.e. Modes of Production always influences the Superstructure in the society.

The class which owns the Forces of Production is always the ruling class. With the change in the nature of the productive forces, relations also undergo changes, creating space for violent revolution and overthrow of existing order. This is known as historical materialism in Marx's interpretation of history.
