In The Communist Manifesto, Karl Marx hypothesized that capitalism would fail if workers revolted and took over the economic system. They would then change this to socialism, and then it would become communism. This was due to excessive tensions between socio-economic classes and with the working class ultimately taking over, as Marx did not believe capitalism would be able to work within the bounds of society.
