Introduction

Abstract

What are the carriers of development in the post-industrial world? Many believe that science and technology are the carriers, because they generate the rapid changes experienced by people in the highly developed countries. Scientific discoveries and technological innovations have had an enormous impact on national economy and particularly on the structure of the labor force, but their influence on family and community life and on the political order have been less marked. But what about the future? Can the accelerated rate of technological and economic change continue, without parallel social and political change? The answer to this question seems to depend in large part on migration, which may turn out to be the carrier of development in the next century.
