After a Christian history of almost 2,000 years, we have come to the age of the managers, an age whose beginning was marked roughly by the end of World War II.

There are many differences between these industrial revolutions, but there is one that is most striking. The industrial revolution is becoming a world revolution. For the first time in the memory of man, there has been wide concern as to whether our human resources are adequate to exploit our technological and productive capacities and to raise the living standards of the world, especially these standards that mark the low per capita income countries.
