Labour worldwide is far less mobile than capital. However, this does not mean that governments can ignore the needs of enterprise or investors. A hundred years ago, mass migration across the Atlantic fuelled the growth of the American economy. Migrants took factory jobs at lower wages. In this day and age, factories are more likely to migrate than workers, mainly because of national barriers against immigration. In such a globalized world, governments must ensure that their economies remain interna- tionally competitive.
