"Private capital tends to become concentrated in few hands, partly because of competition among the capitalists, and partly because technological development and the increasing division of labor encourage the formation of larger units of production at the expense of smaller ones.

This is true since the members of legislative bodies are selected by political parties, largely financed or otherwise influenced by private capitalists"
