 The purpose of dialectical or negative thinking is to expose and then overcome by revolutionary action the contradictions by which advanced industrial societies are constituted. The problem of concealment occurs here because not only does society produce contradictions and the forms of domination that come with them, but also produces the social and psychological mechanisms that conceal these contradictions. An example of a social contradiction is the co-existence of the growth of national wealth and poverty at the same time. Those who own, control, and influence the means of production (the minority) grow richer while the workers (the minority) grow poorer. The idea that the unbridled attempt by the rich to become richer will somehow allow their wealth to trickle down so that all will benefit has been proven false as the gap between the rich and poor continues to grow. However, the trickle down ideology is still very effective. The capitalist belief that unbridled competition is good for everyone conceals the goal of purging society of competition by allowing large corporations to buy out their competition.
