The conflict discussed is the proletariat and the bourgeoisie contrast. The bourgeoisie had a political advantage which played a significant role in a development of the class. The executive of the State managed a lot of affairs of the whole bourgeoisie.
The Manifesto describes conditions of working class under capitalism as a struggle because of rising poverty as a result of low wages. Moreover work didn’t bring people any satisfaction. They felt alienated but had no other choice except making products in order to earn some money and survive.
Capitalism has divided the society into two conflict classes. While bourgeoisie dominated proletariat manufacturing took place and were rapidly developing. Demand for products raised and workers were producing more and more goods. However burned by different revolutions the capitalists couldn’t control the whole proceed which lead to overproduction. Market was no longer able to absorb the products manufactured. Capitalism was doomed. Moreover working class became soldiers that are not appreciated and treated disrespectfully. Therefore workers started forming organizations and clubs where they came up with the ideas to overthrow the ruling class and the proletarian movement began. At this point the bourgeois society was no longer able to protect the proletariat but made it a pauper. Ruling class was about to be abolished.
During the whole history there are examples of a society subdivision into ruling class and a class dominated by the first one. The ideas and priorities of an oppressor have always been of the higher importance and had an impact on the history. That is why “The ruling ideas of each age have always been the ruling ideas if it’s ruling class”.
The proletariat and the communists had nothing to lose but a lot to conquer. They organized themselves into a movement that had an idea and accurate plan how to achieve it. The Proletariat has managed to proclaim themselves as a potential ruling power which is why Karl Marx’s ideas have been proved accurate.
