Patriarchy literally means rule by the father but is taken to refer to the male dominance in society. Kate Millett argued that society is governed by "power-structured relationships, arrangements whereby one group of persons is controlled by another". Secondly, patriarchy is a structure whereby "male shall dominate female".
As a marxist feminist I believe the patriarchy to be a social/economic system that gives power to men in every sphere of life. They dominate through business, media etc,,,, so by making women dissatisfied they create a market in corrective treatments, beauty, fashion etc in which they can seek profit.
