The cognitive dissonance refers to the results of the Fidelity REAL Index, a survey and comparison between effective and estimated retirement provisions in Germany. Whereas the Germans surveyed expect to achieve 70% of their final gross household income upon retirement, they will effectively only make 56%, which reveals a substantive gap between reality and expectations. Other interesting conclusions are available in the Executive Summary in English and the full brochure in German (both made available here with Fidelity's permission).
Similar surveys are currently being conducted in the UK and France. Watch this space.
