This section analyzes how land rent functions as a primary channel of accumulation in agrarian societies with weak industrial development and how it is subsequently transformed and redistributed. It argues that agricultural surplus, once monopolized through private landownership, is appropriated in the form of rent and can even encroach upon what would otherwise be necessary consumption for direct producers. The section then shows how commercial and usury capital interact with rent accumulation, raising rent and interest through mutual reinforcement. Finally, it traces the typical outlets of accumulated rent—urban consumption, land purchases, moneylending, and certain rural processing and trading activities—and explains why, without changes in the underlying mode of accumulation, the transformation of rent into productive industrial capital remains limited.
