These two aspects combined lead to low disposable income and overproduction causing recession. This in turn will push wages down further causing the increasing "immiseration of the proletariat" (Marx 1848).
However Marx did believe that at the time capitalism was a positive industrialising force, and that it was necessary for it to reach its fulfilment before the revolution occurred. This was because a minimal education is necessary for employment in a capitalist society and in order for the proletariat revolution to be successful the proletariat need to be politically educated and class conscious. .
The post revolution aims of a socialist society would be to set up the means to eventually come to a full communist society. The first thing to happen would be the establishment of a dictatorship of the proletariat to oversee the transition and to guard against counter revolution. One of the most important means is that of the "public ownership of the means of production, distribution and exchange." Basically this entails the abolition of private property and the formation of a central bank. .
In a socialist society Marx professed it would be;.
"From each according to his ability, to each according to his work.".
and when that societies aims were met and communism was achieved it would be;.
"From each according to his ability, to each according to his needs.".
Marx claimed that;.
"The Communists do not form a separate party opposed to other working-class parties. They have no interests separate and apart from those of the proletariat as a whole. They do not set up any sectarian principles of their own , by which to shape and mould the proletarian movement." (Marx 1848).
By this one can see that Marx's aims were to create a broad church for all parties and people's of the proletariat. Marx and Engels also believed that the "proletarians have no fatherland", meaning that their allegiance should lie with their class world-wide and not their country.
