Further, there has been stable government, though not always of the most benign sort. Thirdly, it may be that there are some traditional factors in the culture. Those are the three things that I would emphasize. And one of the significant changes is the longer run prospect for urbanization and the drawing of people from agriculture into industry with a higher productive potential. But that is something which I would not emphasize at the expense of the other factors that I've mentioned, namely, emphasis on political stability, education, and cultural investment.
Migration is very important in the history of the West.
There are no new continents to discover. It is still true that in the highly industrialized countries the second and third generation of a labour force don't take very kindly to repetitive, systematized industrial labour. And therefore, one has a steady demand for workers from the worst privations of agriculture in other countries. That is what brings a very large number of Yugoslavs to Germany and Northern Africans to France. It brings very, very large numbers of Mexicans and West Indians to the United States.
