The fruits of the worker's labor accrue to the capitalist, giving him yet more advantage. The capitalist has the pride and the worker has the humiliation. National pride can be offended when rich foreigners bring in capital and use the labors of local workers to extract natural resources for export. Subjective value theory must acknowledge the subjective sense of exploitation, of injustice, even if its monetary quantity is difficult to calculate. For all the claims of private owners rapaciously exploiting natural resources, one fact must be acknowledged.
Private property means responsibility .
By contrast, abolition of ownership opens the door to the public goods problem. The self-interest of all communal owners may dictate a wasteful exploitation of resources. Responsibility for private property must be supplanted by the discipline of statist threats. Marx's admonitions that workers will be rewarded in proportion to their work in the initial phase of communism is not so easily enforced. Workers are faced with incentives to do the least amount of work without being caught.
