Greece, especially after the fall of so-called “existing socialism”, has been transformed into a recipient country for immigrants. An examination, employing Marxist methodology, is undertaken of the social stratification of the foreign labour force in Greece before (2001) and during (2017) the crisis. The changes are highlighted and their causes investigated. In addition to this, a comparison is made between the social stratification of the country's total workforce and that of the foreign workers (2017), and an interpretation offered of the differences that emerge.
