This false- consciousness leads to class conflict where the middle and upper class demonizes the underclass and blames them for their problems. Marx's theories shed light on class conflicts and the struggle over power. Another way Marx's sheds light on gray subjects are his discussions on capitalism. Marx feels that capitalism is intrinsically flawed. The only way for the capitalist to succeed is not by getting an equal amount to what he has given, but instead by getting more than what he has given.
Profit is the goal in capitalism.
The capitalist must produce at an ever-increasing rate while keeping production costs down in order to stay viable. Capitalism does breed innovation and competition. In capitalism everything becomes a commodity. For the Proletariat their ability to work is their only commodity. The Proletariat must sell their labor power to the Bourgeois.
