marxist -
1. class inequality is maintained by the bourgeoisie exploiting the proletariat through keeping wages low and profits high. Whilst the proletariat create the wealth of the bourgeoisie, only a fraction of the surplus value (profit) they create is paid to them in wages. The interests of the bourgeoisie are to control the workers so that they can take as much profit as is possible and to stop the proletariat overthrowing capitalism. The interest of the proletariat is to overthrow the capitalist economic system and create a classless society.
2. the proletariat suffers from a false class consciousness, meaning they are unaware of the true nature of their exploitation. This prevents revolution from taking place. However, a worsening economic crisis will result in the working class realising its exploited state and becoming a class for itself. They will unite in a revolution. Communism would replace capitalism, where the means of production would be shared by the whole community. Everyone would be expected to contribute something to society and instead of wages, they would receive what they needed in terms of food, accommodation, health, care, etc. This would mean that social classes based on economic needs would disappear and communism would result in a classless society.
