Karl Marx, a German revolutionary, emphasized his materialist views on ownership and means of production. He argued that what is most valued is a result of human labour and founded his ideas based on a capitalistic community, meaning a majority of the money is owned by only a small percentage. This causes a distinction between two classes, the industrialists and the working class. The industrialists, the ones that make up the small percentage, own the means of production. The working class are those earning their wages by selling their labour. Problems become noticeable because the upper class is looking to get the most production possible for the least amount of money. Surplus value is created; the profit industrialists hold on to caused by workers producing more than the employers actually need to repay the cost of hiring labourers. Another occurrence is exploitation; when workers receive less money than what their labour is worth. Marx believed that the gap between industrialists and the labourers would continue to grow. The industrialists would become more and more wealthy, and the labourers continue to move towards poverty. Conflict theory is seen throughout relationships and interactions between two groups of people including races, opposite sexes, and religions.
