Migrations and Cultures goes beyond the political view of immigration and presents the whole phenomena of migration and immigration and the major role it plays in the general advancement of the human race.
Most commentators look at the issue of immigration from the viewpoint of immediate politics. In doing so, they focus on only a piece of the issue and lose touch with the larger picture. In "Migrations and Cultures", Thomas Sowell shows the persistence of cultural traits in particular racial and ethnic groups and the role these groups' relocations play in redistributing skills, knowledge, and other forms of "human capital".
