All history is the history of class struggle, changes in modes of production are merely changes is the operation and composition of surplus labor accumulation.

The uniqueness of capitalism is that unlike other modes of surplus accumulation, it creates within itself the means for us to finally break the cycle. While pastoralism and agricultural accumulation was based around usage of slavery or extending the workday to generate surplus, industrial capitalism generates a surplus through a reduction of the necessary labor time for reproduction of the working class. That being said, extension of the workday and slavery are still used in conjunction with technological advancement by capitalists. In the end, technology can't generate profit.
