Talking about migration is meaningless without also talking about the most important of all migrations nowadays: that of capital. In fact the migration of capital is complementary to the migration of people; one cannot be understood without the other. As predicted by Karl Marx (Critique of Political Economy, 1867), capitalism implies that people become more and more things, commodities, that is to say, capital. The migration of people is therefore ultimately one side of the migration of capital. But here we are especially interested in the other side of the coin, in the reciprocal phenomenon: the migration of abstract, volatile capital. Yet this capital is not as abstract as one might think; at the end of the road there are also people of flesh and blood to which this capital returns.
