Human Capital is the talents and capabilities that individuals contribute to the process of production. Human capital also refers to the sum total of skills and knowledge embodied in the ability to perform labor so as to produce economic value. Companies, governments and individuals can invest in this human capital just as they can invest in technology and buildings or in finances. Human capital can be acquired through formal schooling and on-the-job training. There is a complex relationship between the division of labor and human capital. Political capital is built only on a foundation of social capital and human Capital.
