The freer flow of commodities and capital has been one of the features of the contemporary process of globalization. Unlike in the earlier phase of globalization in the 19^th century, however, the freer flow of commodities and capital has not been accompanied by a freer movement of labor globally. The dynamic centers of the global economy, after all, have imposed ever tighter restrictions on migration from the poorer countries.Yet the demand for cheap labor in the richer parts of the world continues to grow, even as more and more people in developing countries seek to escape conditions of economic stagnation and poverty that are often the result of the same dynamics of a system of global capitalism that have created prosperity in the developed world.
