As discipline and methodology in the social sciences,it studies,the relations of production in their complex interaction with the productive forces and the superstructure , Production is a process that take place between man and nature in the course of which man transforms natural substances into a product necessary for human life(llyin and motyley , 1986).
However ,the productive forces are labour , power, objects of labour and means of labour processes. The superstructure denotes those elements such as ; the state ,belief, ideology , and education .
Theories only produce other theories. So if you have money then you have power over the economy, politics, and social status in the eyes of society. You don't need to get too far into this kind of thing, because if you return to the facts of life in the environment all political and social elements collide with each other. So everything starts from the basics, how can you control finances, how can you manage the system in the family and if you are a person working in a certain agency can you maneuver to stay afloat from competitors' political or economic games?
I agree that every institution affects each other. The same way politics affect economics, economics affects politics. However, it should be noted that politics doesn't just revolve government, it is a system that can be found anywhere and hence most (if not all) will say that everything is political if analyzed appropriately.
