9. The labour of the under-developed and less- developed countries, however, provides food for the developed countries and supplies them with raw materials which, when processed industrially, are of greater value than they were on the international market and the increase in value is to the almost exclusive benefit of the developed countries. Thus some countries labour to earn a little and at the same time to enable others to earn much more. 10. As is well known, the fundamental cause of this disequilibrium is the tendency of the demand for industrial products to increase more rapidly than the demand for agricultural products as national income increases. 11. The theory of surplus-value, ennobled by the concept of the human value of labour, inseparable from man himself and from human dignity, served to correct an evident injustice in the domestic socio-economic field, by attaching greater value to labour than that recognized by liberal economic theory and that accorded to it under the capitalist system in its first stages.
