The state sets the framework for the democratic coexistence of citizens and provides services that secure their existence. State finances also support the German economy. State measures and the financing of social systems mitigate economic consequences and damages triggered by crises or unforeseen events such as the corona pandemic or wars. First, a literature review describes the theory of public debt. Then is followed by an analysis of the development of public finances in Germany. The analysis aims to analyse unemployment as a lever. A regression analysis with R explains the development of the debt ratio through the unemployment rate. Subsequently, recommendations on reducing unemployment and the unemployment system should lead to a political discussion.
