In the Marxian theory of distribution, the surplus acquired through capitalist production is split into industrial profit, interest to finance capital, and rent to landlords. The homogeneity within the capitalist class breaks down into fractions of capital which are potentially in conflict with each other. Other fragmentations - between merchant capital and industrial capital, for example - can arise out of the divisions of function within the capitalist system. These fragmentations lead to conflicts of interest within the capitalist class as a whole. Factional struggles which from time to time may become highly destructive are therefore to be expected within the capitalist class.
