(a) A country’s working population, with their existing productive skills and ability, contribute to the creation of the Gross National Product. This is referred to as human resources. So when investment in the form of education, training and medical care is made in human resources, human capital is formed which adds to the country’s Gross National Product which leads to the economic development of a country. Investment in human capital in the form of education and training yields higher incomes earned because of higher productivity by the more educated and better-trained people.
(b) Human Capital is superior to other resources like land and physical capital which are not useful at their own. Human resources can make use of land and capital. So, a large population is not a liability. It can be turned into a productive asset by investment in human capital. For example, by spending on education and health for all, training of industrial and agriculture workers in the use of modern technology etc. development of a country can be increased.
