With the beginning of globalisation in the 1980s, the mobility of many people around the world increased. But that is only half the story, says principal investigator Prof. Dr. Steffen Mau. Today, he says, many people are cut off from mobility opportunities. In the new podcast episode of the Humboldt University Podcast, Steffen Mau talks about transformation processes, about structures of division in society and about how it is possible as a sociologist to write not only scientifically sound but also very personal social analyses.
