His highly controversial books sell in the millions. It all began with "Deutschland schafft sich ab" ("Germany is doing away with itself"). Thilo Sarrazin's 2010 book stimulated a fiery debate over German immigration policy and migrants from Islamic countries.
While critics accused the author of polemics and racism, others claimed that finally, someone was telling the truth. Sarrazin quickly resigned from his management position at Germany's central bank, the Bundesbank, over public pressure but continued to write, issuing books about the euro and what he calls "wishful thinking" in public policy.
A new book has been announced for release this summer, titled "Feindliche Übernahme - wie der Islam den Fortschritt behindert und die Gesellschaft bedroht" (Hostile takeover – how Islam impairs progress and threatens society).
