A country is a big organization. Engineers construct the country. Farmers produce food to feed the country. Military protects the country from the outsiders. Police protect the internal social harmony of the country.
Doctors cure the people of the country.
Politicians rule the country based on the aspirations of the people of the country. Industrialists contribute to the economy of the country. This huge organization and its setup is responsible for all the intellectual heights a human can reach. Family contributes only to his morale. The other things that his family can not give to him are offered by the country.
