The appropriation of surplus products during the development of economic relations takes various forms, but basically it represents the exploitation of someone else's labor, whether that surplus labor is appropriated through kuluks (labor), in finished products (in-kind) or at a later stage of society's development in money. Hence the different names for the forms of alienation of surplus labor, such as: labor rent, natural rent and cash rent. Countries in transition, as well as those underdeveloped countries, are characterized by the collapse of large-scale commodity production and follow the development of crafts and small-scale commodity production, as well as the initial accumulation of capital, where social property becomes private.
