[3] According to Marx, the very same problems that should make capitalism fail should also provide the means for the new, more democratic and egalitarian society to arise.
[5] Here, Marx claims that capitalism's replacement by another economic system is an inevitability, as through time it creates conditions in which it can no longer function.
[5] This part of Marx's argument does not predict what type of system will replace capitalism, it simply stresses the capitalist self-destructive nature.
[5] Marx believed that as non-labor (and by extension of the labor theory, non-profitable) factors become increasingly important, profits will decline, eventually approaching zero.
[7] Next, Marx argued that a post-capitalist system would most likely be one where means of production are collectively owned and democratically controlled (socialism).
