Introduction
Traditionally economists tried to break the shackles of poverty and pave
the way for economic development by means of accumulating material capital.
But in recent years they have downplayed the role of physical capital and have
attached greater importance to human capital. They have now realized that
machines are no more important than the men and women who make them,
maintain them and improve them. In fact, after the Second World War, we find a
clear shift in emphasis toward human potentialities from the potentialities of a
machine, which was the main point of focus right from the time of the
Industrial Revolution
