Economic power means ownership on the means of production and wealth. Economic power affects the political power in many ways. It is believed that those who are financially powerful are also politically powerful, but there is a difference between Liberalism and Marxism about the kind of relationship between economic and political power. According to liberalism, the society that determines political power has many elements which have interdependence and do not define the same political power without the sole economic power. On the other hand, Marxism believes that all kinds of power rest on the economic power and economic power determines the political power in society.
