“Economic approach”: The debt brake is unnecessarily strict. By 2070 it will be well below the Maastricht criterion of 60 percent of gross domestic product.

The FDP insists on it, the Greens and the SPD would like to reform it. According to the experts, this would give the federal government a credit leeway of 36 billion euros per year - at least with a debt ratio below 60 percent. If Germany breaks the criteria, it would still be around 18 billion euros.
