The most scandalous German politician, the author of a sensational super-bestseller with the telling title “Germany: Self-Liquidation”, Thilo Sarrazin, who was practically expelled from his post on the Board of Directors of the German Federal Bank for publishing his intolerant views, asks in this book questions that have become extremely relevant for Europe: How problematic are demographic projections spread over several generations? How do the potential inherent in genes and the influence of the environment interact? Does the Muslim community in Germany strive for integration into German life? What should be the ways out of the migration crisis in which Europe finds itself ?
