The theory of human capital places man at the heart of all production processes and identifies him as the factor determining income growth and a nation’s wealth. Onorato Grassi (2004), in particular, defines human capital as ‘the bringing together of individual resources and acquired knowledge, which are then used to put together theories, projects, solutions and plans of action within a dimension of social interaction and a system of inter-relations.’ These words express the interactive nature of the individual in society, as he or she invests personal resources in the acquisition of knowledge, which is, in turn, used to create and acquire further knowledge, which then furthers the progress of society.
