Observe the world order and see that countries that save and have capital regularly loan to countries that don't save very much that want to borrow it. Capital is no longer a factor of production . The supply of labor, likewise, does not matter. Countries rich in labor supply, such as present day India, are not models of rapid economic growth, nor is it's neighbor China. Observe the close relationship between low unemployment rates and high economic growth rates.

A countries' economy is dependent in the information age on both information and the creativity of its people. Peter Drucker calls it the knowledge world. Information was once a very powerful tool because it was costly to obtain, costly to store and retrieve and costly to use. In fact, management in essence became information. Companies, organizations and governments were and are organized around information.
